process. Supplying multiple logins will create an implicit linked
account. You can only specify one developer provider as part of the

developer provider is the "domain" by which Cognito will refer to your
users.

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.

Merges two users having different IdentityIds, 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
