-- | 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'.

-- Cognito will refer to your users; you provided this domain while
-- creating/updating the identity pool. The developer user identifier is an
-- identifier from your backend that uniquely identifies a user. When you create

-- an expiration time, the token is valid for 15 minutes. You can exchange the
-- token with Amazon STS for temporary AWS credentials, which are valid for a
-- maximum of one hour. The maximum token duration you can set is 24 hours. You
-- should take care in setting the expiration time for a token, as there are
-- significant security implications: an attacker could use a leaked token to
-- access your AWS resources for the token's duration.
