Types

type AssumeRoleInput 

type AssumeRoleInput struct {

	// The duration, in seconds, of the role session. The value can range from 900
	// seconds (15 minutes) to 3600 seconds (1 hour). By default, the value is set
	// to 3600 seconds.
	DurationSeconds *int64 `min:"900" type:"integer"`

	// A unique identifier that is used by third parties when assuming roles in
	// their customers' accounts. For each role that the third party can assume,
	// they should instruct their customers to ensure the role's trust policy checks
	// for the external ID that the third party generated. Each time the third party
	// assumes the role, they should pass the customer's external ID. The external
	// ID is useful in order to help third parties bind a role to the customer who
	// created it. For more information about the external ID, see How to Use an
	// External ID When Granting Access to Your AWS Resources to a Third Party (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_create_for-user_externalid.html)
	// in the Using IAM.
	ExternalId *string `min:"2" type:"string"`

	// An IAM policy in JSON format.
	//
	// This parameter is optional. If you pass a policy, the temporary security
	// credentials that are returned by the operation have the permissions that
	// are allowed by both (the intersection of) the access policy of the role that
	// is being assumed, and the policy that you pass. This gives you a way to further
	// restrict the permissions for the resulting temporary security credentials.
	// You cannot use the passed policy to grant permissions that are in excess
	// of those allowed by the access policy of the role that is being assumed.
	// For more information, see Permissions for AssumeRole, AssumeRoleWithSAML,
	// and AssumeRoleWithWebIdentity (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_control-access_assumerole.html)
	// in the Using IAM.
	//
	// The policy plain text must be 2048 bytes or shorter. However, an internal
	// conversion compresses it into a packed binary format with a separate limit.
	// The PackedPolicySize response element indicates by percentage how close to
	// the upper size limit the policy is, with 100% equaling the maximum allowed
	// size.
	Policy *string `min:"1" type:"string"`

	// The Amazon Resource Name (ARN) of the role to assume.
	RoleArn *string `min:"20" type:"string" required:"true"`

	// An identifier for the assumed role session.
	//
	// Use the role session name to uniquely identify a session when the same role
	// is assumed by different principals or for different reasons. In cross-account
	// scenarios, the role session name is visible to, and can be logged by the
	// account that owns the role. The role session name is also used in the ARN
	// of the assumed role principal. This means that subsequent cross-account API
	// requests using the temporary security credentials will expose the role session
	// name to the external account in their CloudTrail logs.
	RoleSessionName *string `min:"2" type:"string" required:"true"`

	// The identification number of the MFA device that is associated with the user
	// who is making the AssumeRole call. Specify this value if the trust policy
	// of the role being assumed includes a condition that requires MFA authentication.
	// The value is either the serial number for a hardware device (such as GAHT12345678)
	// or an Amazon Resource Name (ARN) for a virtual device (such as arn:aws:iam::123456789012:mfa/user).
	SerialNumber *string `min:"9" type:"string"`

	// The value provided by the MFA device, if the trust policy of the role being
	// assumed requires MFA (that is, if the policy includes a condition that tests
	// for MFA). If the role being assumed requires MFA and if the TokenCode value
	// is missing or expired, the AssumeRole call returns an "access denied" error.
	TokenCode *string `min:"6" type:"string"`
	// contains filtered or unexported fields

	// policy by using the ARN or assumed role ID. The ARN and ID include the RoleSessionName
	// that you specified when you called AssumeRole.
	AssumedRoleUser *AssumedRoleUser `type:"structure"`

	// The temporary security credentials, which include an access key ID, a secret
	// access key, and a security (or session) token.
	//
	// Note: The size of the security token that STS APIs return is not fixed.

The AWS Security Token Service (STS) is a web service that enables you to request temporary, limited-privilege credentials for AWS Identity and Access Management (IAM) users or for users that you authenticate (federated users). This guide provides descriptions of the STS API. For more detailed information about using this service, go to Temporary Security Credentials (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp.html). 

As an alternative to using the API, you can use one of the AWS SDKs, which

consist of libraries and sample code for various programming languages and platforms (Java, Ruby, .NET, iOS, Android, etc.). The SDKs provide a convenient way to create programmatic access to STS. For example, the SDKs take care of cryptographically signing requests, managing errors, and retrying requests automatically. For information about the AWS SDKs, including how to download and install them, see the Tools for Amazon Web Services page (http://aws.amazon.com/tools/). 

For information about setting up signatures and authorization through the

API, go to Signing AWS API Requests (http://docs.aws.amazon.com/general/latest/gr/signing_aws_api_requests.html" target="_blank) in the AWS General Reference. For general information about the Query API, go to Making Query Requests (http://docs.aws.amazon.com/IAM/latest/UserGuide/IAM_UsingQueryAPI.html" target="_blank) in Using IAM. For information about using security tokens with other AWS products, go to AWS Services That Work with IAM (http://docs.aws.amazon.com/IAM/latest/UserGuide/reference_aws-services-that-work-with-iam.html) in the Using IAM.

If you're new to AWS and need additional technical information about a specific AWS product, you can find the product's technical documentation at http://aws.amazon.com/documentation/ (http://aws.amazon.com/documentation/" target="_blank). 

Endpoints

The AWS Security Token Service (STS) has a default endpoint of https://sts.amazonaws.com that maps to the US East (N. Virginia) region. Additional regions are available, but must first be activated in the AWS Management Console before you can use a different region's endpoint. For more information about activating a region for STS see Activating STS in a New Region (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_enable-regions.html) in the Using IAM.

For information about STS endpoints, see Regions and Endpoints (http://docs.aws.amazon.com/general/latest/gr/rande.html#sts_region) in the AWS General Reference. 

Recording API requests

STS supports AWS CloudTrail, which is a service that records AWS calls for your AWS account and delivers log files to an Amazon S3 bucket. By using information collected by CloudTrail, you can determine what requests were successfully made to STS, who made the request, when it was made, and so on. To learn more about CloudTrail, including how to turn it on and find your log files, see the AWS CloudTrail User Guide (http://docs.aws.amazon.com/awscloudtrail/latest/userguide/what_is_cloud_trail_top_level.html). The service client's operations are safe to be used concurrently. It is not safe to mutate any of the client's properties though.

func New 

func New(p client.ConfigProvider, cfgs ...*aws.Config) *STS

New creates a new instance of the STS client with a session. If additional configuration is needed for the client instance use the optional aws.Config parameter to add your extra config.

Example: 

// Create a STS client from just a session.
svc := sts.New(mySession)

// Create a STS client with additional configuration
svc := sts.New(mySession, aws.NewConfig().WithRegion("us-west-2"))

func (*STS) AssumeRole 

func (c *STS) AssumeRole(input *AssumeRoleInput) (*AssumeRoleOutput, error)

Returns a set of temporary security credentials (consisting of an access key ID, a secret access key, and a security token) that you can use to access AWS resources that you might not normally have access to. Typically, you use AssumeRole for cross-account access or federation.

Important: You cannot call AssumeRole by using AWS account credentials; access will be denied. You must use IAM user credentials or temporary security credentials to call AssumeRole.

For cross-account access, imagine that you own multiple accounts and need to access resources in each account. You could create long-term credentials in each account to access those resources. However, managing all those credentials and remembering which one can access which account can be time consuming. Instead, you can create one set of long-term credentials in one account and then use temporary security credentials to access all the other accounts by assuming roles in those accounts. For more information about roles, see IAM Roles (Delegation and Federation) (http://docs.aws.amazon.com/IAM/latest/UserGuide/roles-toplevel.html) in the Using IAM.

For federation, you can, for example, grant single sign-on access to the AWS Management Console. If you already have an identity and authentication system in your corporate network, you don't have to recreate user identities in AWS in order to grant those user identities access to AWS. Instead, after a user has been authenticated, you call AssumeRole (and specify the role with the appropriate permissions) to get temporary security credentials for that user. With those temporary security credentials, you construct a sign-in URL that users can use to access the console. For more information, see Common Scenarios for Temporary Credentials (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp.html#sts-introduction) in the Using IAM.

The temporary security credentials are valid for the duration that you specified when calling AssumeRole, which can be from 900 seconds (15 minutes) to 3600 seconds (1 hour). The default is 1 hour.

Optionally, you can pass an IAM access policy to this operation. If you choose not to pass a policy, the temporary security credentials that are returned by the operation have the permissions that are defined in the access policy of the role that is being assumed. If you pass a policy to this operation, the temporary security credentials that are returned by the operation have the permissions that are allowed by both the access policy of the role that is being assumed, and the policy that you pass. This gives you a way to further restrict the permissions for the resulting temporary security credentials. You cannot use the passed policy to grant permissions that are in excess of those allowed by the access policy of the role that is being assumed. For more information, see Permissions for AssumeRole, AssumeRoleWithSAML, and AssumeRoleWithWebIdentity (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_control-access_assumerole.html) in the Using IAM.

To assume a role, your AWS account must be trusted by the role. The trust relationship is defined in the role's trust policy when the role is created. You must also have a policy that allows you to call sts:AssumeRole. 

Using MFA with AssumeRole

You can optionally include multi-factor authentication (MFA) information when you call AssumeRole. This is useful for cross-account scenarios in which you want to make sure that the user who is assuming the role has been authenticated using an AWS MFA device. In that scenario, the trust policy of the role being assumed includes a condition that tests for MFA authentication; if the caller does not include valid MFA information, the request to assume the role is denied. The condition in a trust policy that tests for MFA authentication might look like the following example. 

"Condition": {"Bool": {"aws:MultiFactorAuthPresent": true}}

For more information, see Configuring MFA-Protected API Access (http://docs.aws.amazon.com/IAM/latest/UserGuide/MFAProtectedAPI.html) in the Using IAM guide.

To use MFA with AssumeRole, you pass values for the SerialNumber and TokenCode parameters. The SerialNumber value identifies the user's hardware or virtual MFA device. The TokenCode is the time-based one-time password (TOTP) that the MFA devices produces.

Example 
package main

import (
	"fmt"

	"github.com/aws/aws-sdk-go/aws"
	"github.com/aws/aws-sdk-go/aws/session"
	"github.com/aws/aws-sdk-go/service/sts"
)

func main() {
	svc := sts.New(session.New())

	params := &sts.AssumeRoleInput{
		RoleArn:         aws.String("arnType"),             // Required
		RoleSessionName: aws.String("roleSessionNameType"), // Required
		DurationSeconds: aws.Int64(1),
		ExternalId:      aws.String("externalIdType"),
		Policy:          aws.String("sessionPolicyDocumentType"),
		SerialNumber:    aws.String("serialNumberType"),
		TokenCode:       aws.String("tokenCodeType"),
	}
	resp, err := svc.AssumeRole(params)

	if err != nil {
		// Print the error, cast err to awserr.Error to get the Code and
		// Message from an error.
		fmt.Println(err.Error())
		return
	}

	// Pretty-print the response data.
	fmt.Println(resp)
}

Output:

func (*STS) AssumeRoleRequest 

func (c *STS) AssumeRoleRequest(input *AssumeRoleInput) (req *request.Request, output *AssumeRoleOutput)

AssumeRoleRequest generates a request for the AssumeRole operation.

func (*STS) AssumeRoleWithSAML 

func (c *STS) AssumeRoleWithSAML(input *AssumeRoleWithSAMLInput) (*AssumeRoleWithSAMLOutput, error)

Returns a set of temporary security credentials for users who have been authenticated via a SAML authentication response. This operation provides a mechanism for tying an enterprise identity store or directory to role-based AWS access without user-specific credentials or configuration.

The temporary security credentials returned by this operation consist of an access key ID, a secret access key, and a security token. Applications can use these temporary security credentials to sign calls to AWS services. The credentials are valid for the duration that you specified when calling AssumeRoleWithSAML, which can be up to 3600 seconds (1 hour) or until the time specified in the SAML authentication response's SessionNotOnOrAfter value, whichever is shorter.

The maximum duration for a session is 1 hour, and the minimum duration is 15 minutes, even if values outside this range are specified. Optionally, you can pass an IAM access policy to this operation. If you choose not to pass a policy, the temporary security credentials that are returned by the operation have the permissions that are defined in the access policy of the role that is being assumed. If you pass a policy to this operation, the temporary security credentials that are returned by the operation have the permissions that are allowed by both the access policy of the role that is being assumed, and the policy that you pass. This gives you a way to further restrict the permissions for the resulting temporary security credentials. You cannot use the passed policy to grant permissions that are in excess of those allowed by the access policy of the role that is being assumed. For more information, see Permissions for AssumeRole, AssumeRoleWithSAML, and AssumeRoleWithWebIdentity (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_control-access_assumerole.html) in the Using IAM.

Before your application can call AssumeRoleWithSAML, you must configure your SAML identity provider (IdP) to issue the claims required by AWS. Additionally, you must use AWS Identity and Access Management (IAM) to create a SAML provider entity in your AWS account that represents your identity provider, and create an IAM role that specifies this SAML provider in its trust policy.

Calling AssumeRoleWithSAML does not require the use of AWS security credentials. The identity of the caller is validated by using keys in the metadata document that is uploaded for the SAML provider entity for your identity provider.

		return
	}

	// Pretty-print the response data.
	fmt.Println(resp)
}

Output:

func (*STS) AssumeRoleWithSAMLRequest 

func (c *STS) AssumeRoleWithSAMLRequest(input *AssumeRoleWithSAMLInput) (req *request.Request, output *AssumeRoleWithSAMLOutput)

AssumeRoleWithSAMLRequest generates a request for the AssumeRoleWithSAML operation.

func (*STS) AssumeRoleWithWebIdentity 

func (c *STS) AssumeRoleWithWebIdentity(input *AssumeRoleWithWebIdentityInput) (*AssumeRoleWithWebIdentityOutput, error)

Returns a set of temporary security credentials for users who have been authenticated in a mobile or web application with a web identity provider, such as Amazon Cognito, Login with Amazon, Facebook, Google, or any OpenID Connect-compatible identity provider. 

For mobile applications, we recommend that you use Amazon Cognito. You

can use Amazon Cognito with the AWS SDK for iOS (http://aws.amazon.com/sdkforios/) and the AWS SDK for Android (http://aws.amazon.com/sdkforandroid/) to uniquely identify a user and supply the user with a consistent identity throughout the lifetime of an application.

To learn more about Amazon Cognito, see Amazon Cognito Overview (http://docs.aws.amazon.com/mobile/sdkforandroid/developerguide/cognito-auth.html#d0e840) in the AWS SDK for Android Developer Guide guide and Amazon Cognito Overview (http://docs.aws.amazon.com/mobile/sdkforios/developerguide/cognito-auth.html#d0e664) in the AWS SDK for iOS Developer Guide. 

Calling AssumeRoleWithWebIdentity does not require the use of AWS security

credentials. Therefore, you can distribute an application (for example, on mobile devices) that requests temporary security credentials without including long-term AWS credentials in the application, and without deploying server-based proxy services that use long-term AWS credentials. Instead, the identity of the caller is validated by using a token from the web identity provider.

The temporary security credentials returned by this API consist of an access key ID, a secret access key, and a security token. Applications can use these temporary security credentials to sign calls to AWS service APIs. The credentials are valid for the duration that you specified when calling AssumeRoleWithWebIdentity, which can be from 900 seconds (15 minutes) to 3600 seconds (1 hour). By default, the temporary security credentials are valid for 1 hour.

Optionally, you can pass an IAM access policy to this operation. If you choose not to pass a policy, the temporary security credentials that are returned by the operation have the permissions that are defined in the access policy of the role that is being assumed. If you pass a policy to this operation, the temporary security credentials that are returned by the operation have the permissions that are allowed by both the access policy of the role that is being assumed, and the policy that you pass. This gives you a way to further restrict the permissions for the resulting temporary security credentials. You cannot use the passed policy to grant permissions that are in excess of those allowed by the access policy of the role that is being assumed. For more information, see Permissions for AssumeRole, AssumeRoleWithSAML, and AssumeRoleWithWebIdentity (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_control-access_assumerole.html) in the Using IAM.

Before your application can call AssumeRoleWithWebIdentity, you must have an identity token from a supported identity provider and create a role that the application can assume. The role that your application assumes must trust the identity provider that is associated with the identity token. In other words, the identity provider must be specified in the role's trust policy.

For more information about how to use web identity federation and the AssumeRoleWithWebIdentity API, see the following resources:

and Federation Through a Web-based Identity Provider (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#api_assumerolewithwebidentity). 

Web Identity Federation Playground (https://web-identity-federation-playground.s3.amazonaws.com/index.html).

This interactive website lets you walk through the process of authenticating via Login with Amazon, Facebook, or Google, getting temporary security credentials, and then using those credentials to make a request to AWS. AWS SDK for iOS (http://aws.amazon.com/sdkforios/) and AWS SDK for Android (http://aws.amazon.com/sdkforandroid/). These toolkits contain sample apps that show how to invoke the identity providers, and then how to use the information from these providers to get and use temporary security credentials. Web Identity Federation with Mobile Applications (http://aws.amazon.com/articles/4617974389850313). This article discusses web identity federation and shows an example of how to use web identity federation to get access to content in Amazon S3.

		fmt.Println(err.Error())
		return
	}

	// Pretty-print the response data.
	fmt.Println(resp)
}

Output:

func (*STS) AssumeRoleWithWebIdentityRequest 

func (c *STS) AssumeRoleWithWebIdentityRequest(input *AssumeRoleWithWebIdentityInput) (req *request.Request, output *AssumeRoleWithWebIdentityOutput)

AssumeRoleWithWebIdentityRequest generates a request for the AssumeRoleWithWebIdentity operation.

func (*STS) DecodeAuthorizationMessage 

func (c *STS) DecodeAuthorizationMessage(input *DecodeAuthorizationMessageInput) (*DecodeAuthorizationMessageOutput, error)

Decodes additional information about the authorization status of a request from an encoded message returned in response to an AWS request.

For example, if a user is not authorized to perform an action that he or she has requested, the request returns a Client.UnauthorizedOperation response (an HTTP 403 response). Some AWS actions additionally return an encoded message that can provide details about this authorization failure. 

Only certain AWS actions return an encoded authorization message. The documentation

for an individual action indicates whether that action returns an encoded message in addition to returning an HTTP code. The message is encoded because the details of the authorization status can constitute privileged information that the user who requested the action should not see. To decode an authorization status message, a user must be granted permissions via an IAM policy to request the DecodeAuthorizationMessage (sts:DecodeAuthorizationMessage) action.

The decoded message includes the following type of information: 

Whether the request was denied due to an explicit deny or due to the absence

of an explicit allow. For more information, see Determining Whether a Request is Allowed or Denied (http://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_evaluation-logic.html#policy-eval-denyallow) in the Using IAM. The principal who made the request. The requested action. The requested resource. The values of condition keys in the context of the user's request.

Example 
package main

import (
	"fmt"

	"github.com/aws/aws-sdk-go/aws"
	"github.com/aws/aws-sdk-go/aws/session"
	"github.com/aws/aws-sdk-go/service/sts"
)

func main() {
	svc := sts.New(session.New())

	params := &sts.DecodeAuthorizationMessageInput{
		EncodedMessage: aws.String("encodedMessageType"), // Required
	}
	resp, err := svc.DecodeAuthorizationMessage(params)

	if err != nil {
		// Print the error, cast err to awserr.Error to get the Code and
		// Message from an error.
		fmt.Println(err.Error())
		return
	}

	// Pretty-print the response data.
	fmt.Println(resp)
}

Output:

func (*STS) DecodeAuthorizationMessageRequest 

func (c *STS) DecodeAuthorizationMessageRequest(input *DecodeAuthorizationMessageInput) (req *request.Request, output *DecodeAuthorizationMessageOutput)

DecodeAuthorizationMessageRequest generates a request for the DecodeAuthorizationMessage operation.

func (*STS) GetFederationToken 

func (c *STS) GetFederationToken(input *GetFederationTokenInput) (*GetFederationTokenOutput, error)

Returns a set of temporary security credentials (consisting of an access key ID, a secret access key, and a security token) for a federated user. A typical use is in a proxy application that gets temporary security credentials on behalf of distributed applications inside a corporate network. Because you must call the GetFederationToken action using the long-term security credentials of an IAM user, this call is appropriate in contexts where those credentials can be safely stored, usually in a server-based application. 

If you are creating a mobile-based or browser-based app that can authenticate

users using a web identity provider like Login with Amazon, Facebook, Google, or an OpenID Connect-compatible identity provider, we recommend that you use Amazon Cognito (http://aws.amazon.com/cognito/) or AssumeRoleWithWebIdentity. For more information, see Federation Through a Web-based Identity Provider (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#api_assumerolewithwebidentity). 

The GetFederationToken action must be called by using the long-term AWS

security credentials of an IAM user. You can also call GetFederationToken using the security credentials of an AWS account (root), but this is not recommended. Instead, we recommend that you create an IAM user for the purpose of the proxy application and then attach a policy to the IAM user that limits federated users to only the actions and resources they need access to. For more information, see IAM Best Practices (http://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html) in the Using IAM.

The temporary security credentials that are obtained by using the long-term credentials of an IAM user are valid for the specified duration, between 900 seconds (15 minutes) and 129600 seconds (36 hours). Temporary credentials that are obtained by using AWS account (root) credentials have a maximum duration of 3600 seconds (1 hour) 

Permissions

The permissions for the temporary security credentials returned by GetFederationToken are determined by a combination of the following: 

The policy or policies that are attached to the IAM user whose credentials

are used to call GetFederationToken. The policy that is passed as a parameter in the call. The passed policy is attached to the temporary security credentials that result from the GetFederationToken API call--that is, to the federated user. When the federated user makes an AWS request, AWS evaluates the policy attached to the federated user in combination with the policy or policies attached to the IAM user whose credentials were used to call GetFederationToken. AWS allows the federated user's request only when both the federated user and the IAM user are explicitly allowed to perform the requested action. The passed policy cannot grant more permissions than those that are defined in the IAM user policy.

A typical use case is that the permissions of the IAM user whose credentials are used to call GetFederationToken are designed to allow access to all the actions and resources that any federated user will need. Then, for individual users, you pass a policy to the operation that scopes down the permissions to a level that's appropriate to that individual user, using a policy that allows only a subset of permissions that are granted to the IAM user.

If you do not pass a policy, the resulting temporary security credentials have no effective permissions. The only exception is when the temporary security credentials are used to access a resource that has a resource-based policy that specifically allows the federated user to access the resource.

For more information about how permissions work, see Permissions for GetFederationToken (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_control-access_getfederationtoken.html). For information about using GetFederationToken to create temporary security credentials, see GetFederationToken—Federation Through a Custom Identity Broker (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#api_getfederationtoken).

Example 
package main

import (
	"fmt"

	"github.com/aws/aws-sdk-go/aws"
	"github.com/aws/aws-sdk-go/aws/session"
	"github.com/aws/aws-sdk-go/service/sts"
)

func main() {
	svc := sts.New(session.New())

	params := &sts.GetFederationTokenInput{
		Name:            aws.String("userNameType"), // Required
		DurationSeconds: aws.Int64(1),
		Policy:          aws.String("sessionPolicyDocumentType"),
	}
	resp, err := svc.GetFederationToken(params)

	if err != nil {
		// Print the error, cast err to awserr.Error to get the Code and
		// Message from an error.
		fmt.Println(err.Error())
		return
	}

	// Pretty-print the response data.
	fmt.Println(resp)
}

Output:

func (*STS) GetFederationTokenRequest 

func (c *STS) GetFederationTokenRequest(input *GetFederationTokenInput) (req *request.Request, output *GetFederationTokenOutput)

GetFederationTokenRequest generates a request for the GetFederationToken operation.

func (*STS) GetSessionToken 

func (c *STS) GetSessionToken(input *GetSessionTokenInput) (*GetSessionTokenOutput, error)

Returns a set of temporary credentials for an AWS account or IAM user. The credentials consist of an access key ID, a secret access key, and a security token. Typically, you use GetSessionToken if you want to use MFA to protect programmatic calls to specific AWS APIs like Amazon EC2 StopInstances. MFA-enabled IAM users would need to call GetSessionToken and submit an MFA code that is associated with their MFA device. Using the temporary security credentials that are returned from the call, IAM users can then make programmatic calls to APIs that require MFA authentication. If you do not supply a correct MFA code, then the API returns an access denied error.

The GetSessionToken action must be called by using the long-term AWS security credentials of the AWS account or an IAM user. Credentials that are created by IAM users are valid for the duration that you specify, between 900 seconds (15 minutes) and 129600 seconds (36 hours); credentials that are created by using account credentials have a maximum duration of 3600 seconds (1 hour). 

We recommend that you do not call GetSessionToken with root account credentials.

Instead, follow our best practices (http://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#create-iam-users) by creating one or more IAM users, giving them the necessary permissions, and using IAM users for everyday interaction with AWS. 

The permissions associated with the temporary security credentials returned

by GetSessionToken are based on the permissions associated with account or IAM user whose credentials are used to call the action. If GetSessionToken is called using root account credentials, the temporary credentials have root account permissions. Similarly, if GetSessionToken is called using the credentials of an IAM user, the temporary credentials have the same permissions as the IAM user.

For more information about using GetSessionToken to create temporary credentials, go to Temporary Credentials for Users in Untrusted Environments (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#api_getsessiontoken) in the Using IAM.
