	DynamicLinkDomain     string `json:"dynamicLinkDomain,omitempty"`
}

ActionCodeSettings specifies the required continue/state URL with optional Android and iOS settings. Used when invoking the email action link generation APIs.

type Client 

type Client struct {
	TenantManager *TenantManager
	// contains filtered or unexported fields
}

Client is the interface for the Firebase auth service.

Client facilitates generating custom JWT tokens for Firebase clients, and verifying ID tokens issued by Firebase backend services.

func NewClient 

func NewClient(ctx context.Context, conf *internal.AuthConfig) (*Client, error)

NewClient creates a new instance of the Firebase Auth Client.

This function can only be invoked from within the SDK. Client applications should access the Auth service through firebase.App.

func (Client) CreateOIDCProviderConfig 

func (c Client) CreateOIDCProviderConfig(ctx context.Context, config *OIDCProviderConfigToCreate) (*OIDCProviderConfig, error)

CreateOIDCProviderConfig creates a new OIDC provider config from the given parameters.

func (Client) CreateSAMLProviderConfig 

func (c Client) CreateSAMLProviderConfig(ctx context.Context, config *SAMLProviderConfigToCreate) (*SAMLProviderConfig, error)

func (Client) CreateUser 

func (c Client) CreateUser(ctx context.Context, user *UserToCreate) (*UserRecord, error)

CreateUser creates a new user with the specified properties.

func (*Client) CustomToken 

func (c *Client) CustomToken(ctx context.Context, uid string) (string, error)

CustomToken creates a signed custom authentication token with the specified user ID.

The resulting JWT can be used in a Firebase client SDK to trigger an authentication flow. See https://firebase.google.com/docs/auth/admin/create-custom-tokens#sign_in_using_custom_tokens_on_clients for more details on how to use custom tokens for client authentication.

CustomToken follows the protocol outlined below to sign the generated tokens:

  • If the SDK was initialized with service account credentials, uses the private key present in the credentials to sign tokens locally.
  • If a service account email was specified during initialization (via firebase.Config struct), calls the IAM service with that email to sign tokens remotely. See https://cloud.google.com/iam/reference/rest/v1/projects.serviceAccounts/signBlob.
  • If the code is deployed in the Google App Engine standard environment, uses the App Identity service to sign tokens. See https://cloud.google.com/appengine/docs/standard/go/reference#SignBytes.
  • If the code is deployed in a different GCP-managed environment (e.g. Google Compute Engine), uses the local Metadata server to auto discover a service account email. This is used in conjunction with the IAM service to sign tokens remotely.

CustomToken returns an error the SDK fails to discover a viable mechanism for signing tokens.

func (*Client) CustomTokenWithClaims 

func (c *Client) CustomTokenWithClaims(ctx context.Context, uid string, devClaims map[string]interface{}) (string, error)

RevokeRefreshTokens updates the user's TokensValidAfterMillis to the current UTC second. It is important that the server on which this is called has its clock set correctly and synchronized.

While this revokes all sessions for a specified user and disables any new ID tokens for existing sessions from getting minted, existing ID tokens may remain active until their natural expiration (one hour). To verify that ID tokens are revoked, use `verifyIdTokenAndCheckRevoked(ctx, idToken)`.

func (Client) SAMLProviderConfig 

func (c Client) SAMLProviderConfig(ctx context.Context, id string) (*SAMLProviderConfig, error)

SAMLProviderConfig returns the SAMLProviderConfig with the given ID.

func (c *Client) SessionCookie(
	ctx context.Context,
	idToken string,
	expiresIn time.Duration,
) (string, error)

SessionCookie creates a new Firebase session cookie from the given ID token and expiry duration. The returned JWT can be set as a server-side session cookie with a custom cookie policy. Expiry duration must be at least 5 minutes but may not exceed 14 days.

func (Client) SetCustomUserClaims 

func (c Client) SetCustomUserClaims(ctx context.Context, uid string, customClaims map[string]interface{}) error

SetCustomUserClaims sets additional claims on an existing user account.

Custom claims set via this function can be used to define user roles and privilege levels. These claims propagate to all the devices where the user is already signed in (after token expiration or when token refresh is forced), and next time the user signs in. The claims can be accessed via the user's ID token JWT. If a reserved OIDC claim is specified (sub, iat, iss, etc), an error is thrown. Claims payload must also not be larger then 1000 characters when serialized into a JSON string.

func (Client) UpdateOIDCProviderConfig 

func (c Client) UpdateOIDCProviderConfig(ctx context.Context, id string, config *OIDCProviderConfigToUpdate) (*OIDCProviderConfig, error)

func (Client) VerifyIDToken 

func (c Client) VerifyIDToken(ctx context.Context, idToken string) (*Token, error)

VerifyIDToken verifies the signature and payload of the provided ID token.

VerifyIDToken accepts a signed JWT token string, and verifies that it is current, issued for the correct Firebase project, and signed by the Google Firebase services in the cloud. It returns a Token containing the decoded claims in the input JWT. See https://firebase.google.com/docs/auth/admin/verify-id-tokens#retrieve_id_tokens_on_clients for more details on how to obtain an ID token in a client app.

This function does not make any RPC calls most of the time. The only time it makes an RPC call is when Google public keys need to be refreshed. These keys get cached up to 24 hours, and therefore the RPC overhead gets amortized over many invocations of this function.

This does not check whether or not the token has been revoked. Use `VerifyIDTokenAndCheckRevoked()` when a revocation check is needed.

func (Client) VerifyIDTokenAndCheckRevoked 

func (c Client) VerifyIDTokenAndCheckRevoked(ctx context.Context, idToken string) (*Token, error)

VerifyIDTokenAndCheckRevoked verifies the provided ID token, and additionally checks that the token has not been revoked.

This function uses `VerifyIDToken()` internally to verify the ID token JWT. However, unlike `VerifyIDToken()` this function must make an RPC call to perform the revocation check. Developers are advised to take this additional overhead into consideration when including this function in an authorization flow that gets executed often.

func (*Client) VerifySessionCookie 

func (c *Client) VerifySessionCookie(ctx context.Context, sessionCookie string) (*Token, error)

VerifySessionCookie verifies the signature and payload of the provided Firebase session cookie.

VerifySessionCookie accepts a signed JWT token string, and verifies that it is current, issued for the correct Firebase project, and signed by the Google Firebase services in the cloud. It returns a Token containing the decoded claims in the input JWT. See https://firebase.google.com/docs/auth/admin/manage-cookies for more details on how to obtain a session cookie.

This function does not make any RPC calls most of the time. The only time it makes an RPC call is when Google public keys need to be refreshed. These keys get cached up to 24 hours, and therefore the RPC overhead gets amortized over many invocations of this function.

This does not check whether or not the cookie has been revoked. Use `VerifySessionCookieAndCheckRevoked()` when a revocation check is needed.

func (*Client) VerifySessionCookieAndCheckRevoked 

func (c *Client) VerifySessionCookieAndCheckRevoked(ctx context.Context, sessionCookie string) (*Token, error)

VerifySessionCookieAndCheckRevoked verifies the provided session cookie, and additionally checks that the cookie has not been revoked.

This function uses `VerifySessionCookie()` internally to verify the cookie JWT. However, unlike `VerifySessionCookie()` this function must make an RPC call to perform the revocation check. Developers are advised to take this additional overhead into consideration when including this function in an authorization flow that gets executed often.

	EnableEmailLinkSignIn bool   `json:"enableEmailLinkSignin"`
}

Tenant represents a tenant in a multi-tenant application.

Multi-tenancy support requires Google Cloud's Identity Platform (GCIP). To learn more about GCIP, including pricing and features, see https://cloud.google.com/identity-platform.

Before multi-tenancy can be used in a Google Cloud Identity Platform project, tenants must be enabled in that project via the Cloud Console UI.

A tenant configuration provides information such as the display name, tenant identifier and email authentication configuration. For OIDC/SAML provider configuration management, TenantClient instances should be used instead of a Tenant to retrieve the list of configured IdPs on a tenant. When configuring these providers, note that tenants will inherit whitelisted domains and authenticated redirect URIs of their parent project.

All other settings of a tenant will also be inherited. These will need to be managed from the Cloud Console UI.

type TenantClient 

type TenantClient struct {
	// contains filtered or unexported fields
}

TenantClient is used for managing users, configuring SAML/OIDC providers, and generating email links for specific tenants.

Before multi-tenancy can be used in a Google Cloud Identity Platform project, tenants must be enabled in that project via the Cloud Console UI.

Each tenant contains its own identity providers, settings and users. TenantClient enables managing users and SAML/OIDC configurations of specific tenants. It also supports verifying ID tokens issued to users who are signed into specific tenants.

TenantClient instances for a specific tenantID can be instantiated by calling [TenantManager.AuthForTenant(tenantID)].

RevokeRefreshTokens updates the user's TokensValidAfterMillis to the current UTC second. It is important that the server on which this is called has its clock set correctly and synchronized.

While this revokes all sessions for a specified user and disables any new ID tokens for existing sessions from getting minted, existing ID tokens may remain active until their natural expiration (one hour). To verify that ID tokens are revoked, use `verifyIdTokenAndCheckRevoked(ctx, idToken)`.

func (TenantClient) SAMLProviderConfig 

func (c TenantClient) SAMLProviderConfig(ctx context.Context, id string) (*SAMLProviderConfig, error)

SAMLProviderConfig returns the SAMLProviderConfig with the given ID.

func (TenantClient) SAMLProviderConfigs 

func (c TenantClient) SAMLProviderConfigs(ctx context.Context, nextPageToken string) *SAMLProviderConfigIterator

SAMLProviderConfigs returns an iterator over SAML provider configurations.

If nextPageToken is empty, the iterator will start at the beginning. Otherwise, iterator starts after the token.

func (TenantClient) SetCustomUserClaims 

func (c TenantClient) SetCustomUserClaims(ctx context.Context, uid string, customClaims map[string]interface{}) error

SetCustomUserClaims sets additional claims on an existing user account.

Custom claims set via this function can be used to define user roles and privilege levels. These claims propagate to all the devices where the user is already signed in (after token expiration or when token refresh is forced), and next time the user signs in. The claims can be accessed via the user's ID token JWT. If a reserved OIDC claim is specified (sub, iat, iss, etc), an error is thrown. Claims payload must also not be larger then 1000 characters when serialized into a JSON string.

func (*TenantClient) TenantID 

func (tc *TenantClient) TenantID() string

TenantID returns the ID of the tenant to which this TenantClient instance belongs.

func (TenantClient) UpdateOIDCProviderConfig 

func (c TenantClient) UpdateOIDCProviderConfig(ctx context.Context, id string, config *OIDCProviderConfigToUpdate) (*OIDCProviderConfig, error)

func (TenantClient) UpdateSAMLProviderConfig 

func (c TenantClient) UpdateSAMLProviderConfig(ctx context.Context, id string, config *SAMLProviderConfigToUpdate) (*SAMLProviderConfig, error)

UpdateSAMLProviderConfig updates an existing SAML provider config with the given parameters.

func (TenantClient) UpdateUser 

func (c TenantClient) UpdateUser(
	ctx context.Context, uid string, user *UserToUpdate) (ur *UserRecord, err error)

func (TenantClient) Users 

func (c TenantClient) Users(ctx context.Context, nextPageToken string) *UserIterator

Users returns an iterator over Users.

If nextPageToken is empty, the iterator will start at the beginning. If the nextPageToken is not empty, the iterator starts after the token.

func (TenantClient) VerifyIDToken 

func (c TenantClient) VerifyIDToken(ctx context.Context, idToken string) (*Token, error)

VerifyIDToken verifies the signature and payload of the provided ID token.

VerifyIDToken accepts a signed JWT token string, and verifies that it is current, issued for the correct Firebase project, and signed by the Google Firebase services in the cloud. It returns a Token containing the decoded claims in the input JWT. See https://firebase.google.com/docs/auth/admin/verify-id-tokens#retrieve_id_tokens_on_clients for more details on how to obtain an ID token in a client app.

This function does not make any RPC calls most of the time. The only time it makes an RPC call is when Google public keys need to be refreshed. These keys get cached up to 24 hours, and therefore the RPC overhead gets amortized over many invocations of this function.

This does not check whether or not the token has been revoked. Use `VerifyIDTokenAndCheckRevoked()` when a revocation check is needed.

func (TenantClient) VerifyIDTokenAndCheckRevoked 

func (c TenantClient) VerifyIDTokenAndCheckRevoked(ctx context.Context, idToken string) (*Token, error)

VerifyIDTokenAndCheckRevoked verifies the provided ID token, and additionally checks that the token has not been revoked.

This function uses `VerifyIDToken()` internally to verify the ID token JWT. However, unlike `VerifyIDToken()` this function must make an RPC call to perform the revocation check. Developers are advised to take this additional overhead into consideration when including this function in an authorization flow that gets executed often.
