README

Auth package

The CLI authentication follows this approach:

1. $ auth0 login uses Auth0 Device Flow to get an acccess token and a refresh token for the selected tenant.
2. The access token is stored at the configuration file.
3. The refresh token is stored at the OS keychain (supports macOS, Linux, and Windows thanks to https://github.com/zalando/go-keyring).
4. During regular commands initialization, the access token is used to instantiate an Auth0 API client. - If the token is expired according to the value stored on the configuration file, a new one is requested using the refresh token. - In case of any error, the interactive login flow is triggered.

	Audience           string
	ClientID           string
	DeviceCodeEndpoint string
	OauthTokenEndpoint string
}

func (*Authenticator) Start

func (a *Authenticator) Start(ctx context.Context) (State, error)

Start kicks-off the device authentication flow by requesting a device code from Auth0, The returned state contains the URI for the next step of the flow.

func (*Authenticator) Wait

func (a *Authenticator) Wait(ctx context.Context, state State) (Result, error)

Wait waits until the user is logged in on the browser.

type Keyring

type Keyring struct{}

func (*Keyring) Delete

func (k *Keyring) Delete(namespace, key string) error

Delete deletes a value for the given namespace and key.

func (*Keyring) Get

func (k *Keyring) Get(namespace, key string) (string, error)

Get gets a value for the given namespace and key.

func (*Keyring) Set

func (k *Keyring) Set(namespace, key, value string) error

func (*TokenRetriever) Delete

func (t *TokenRetriever) Delete(tenant string) error

Delete deletes the given tenant from the secrets storage.

func (*TokenRetriever) Refresh

func (t *TokenRetriever) Refresh(ctx context.Context, tenant string) (TokenResponse, error)

Refresh gets a new access token from the provided refresh token, The request is used the default client_id and endpoint for device authentication.
