public interface AmazonCognitoIdentity
Amazon Cognito is a web service that delivers scoped temporary credentials to mobile devices and other untrusted environments. Amazon Cognito uniquely identifies a device and supplies the user with a consistent identity over the lifetime of an application.
Using Amazon Cognito, you can enable authentication with one or more third-party identity providers (Facebook, Google, or Login with Amazon), and you can also choose to support unauthenticated access from your app. Cognito delivers a unique identifier for each user and acts as an OpenID token provider trusted by AWS Security Token Service (STS) to access temporary, limited-privilege AWS credentials.
To provide end-user credentials, first make an unsigned call to GetId.
If the end user is authenticated with one of the supported identity
providers, set the Logins
map with the identity provider
token. GetId
returns a unique identifier for the user.
Next, make an unsigned call to GetCredentialsForIdentity. This call
expects the same Logins
map as the GetId
call, as well as the IdentityID
originally returned by
GetId
. Assuming your identity pool has been configured
via the SetIdentityPoolRoles operation,
GetCredentialsForIdentity
will return AWS credentials for
your use. If your pool has not been configured with
SetIdentityPoolRoles
, or if you want to follow legacy
flow, make an unsigned call to GetOpenIdToken, which returns the
OpenID token necessary to call STS and retrieve AWS credentials. This
call expects the same Logins
map as the
GetId
call, as well as the IdentityID
originally returned by GetId
. The token returned by
GetOpenIdToken
can be passed to the STS operation
AssumeRoleWithWebIdentity
to retrieve AWS credentials.
If you want to use Amazon Cognito in an Android, iOS, or Unity application, you will probably want to make API calls via the AWS Mobile SDK. To learn more, see the AWS Mobile SDK Developer Guide .

Callers can pass in just the endpoint (ex: "cognito-identity.us-east-1.amazonaws.com/") or a full

Merges two users having different IdentityId
s, existing
in the same identity pool, and identified by the same developer
provider. You can use this action to request that discrete users be
merged and identified as a single user in the Cognito environment.
Cognito associates the given source user (
SourceUserIdentifier
) with the IdentityId
of the DestinationUserIdentifier
. Only
developer-authenticated users can be merged. If the users to be merged
are associated with the same public provider, but as two different
users, an exception will be thrown.

Registers (or retrieves) a Cognito IdentityId
and an
OpenID Connect token for a user authenticated by your backend
authentication process. Supplying multiple logins will create an
implicit linked account. You can only specify one developer provider
as part of the Logins
map, which is linked to the
identity pool. The developer provider is the "domain" by which Cognito
will refer to your users.
You can use GetOpenIdTokenForDeveloperIdentity
to create
a new identity and to link new logins (that is, user credentials
issued by a public provider or developer provider) to an existing
identity. When you want to create a new identity, the
IdentityId
should be null. When you want to associate a
new login with an existing authenticated/unauthenticated identity, you
can do so by providing the existing IdentityId
. This API
will create the identity in the specified IdentityPoolId
.
You must use AWS Developer credentials to call this API.
