Amazon Cognito Federated Identities
Amazon Cognito Federated Identities is a web service that delivers scoped temporary credentials to mobile devices and other untrusted environments.
It uniquely identifies a device and supplies the user with a consistent identity over the lifetime of an application.
Using Amazon Cognito Federated Identities, you can enable authentication with one or more third-party identity providers (Facebook, Google, or Login with Amazon) or an Amazon Cognito user pool, 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.
For a description of the authentication flow from the Amazon Cognito Developer Guide see Authentication Flow.
For more information see Amazon Cognito Federated Identities.

Creates a new identity pool.
The identity pool is a store of user identity
information that is specific to your AWS account. The keys for
SupportedLoginProviders
are as follows:
*
Facebook: graph.facebook.com
*
Google: accounts.google.com
*
Amazon: www.amazon.com

You must use AWS Developer credentials to call this API.
Returns credentials for the provided identity ID.
Any provided logins will be validated against supported login providers. If the token is for cognito-identity.amazonaws.com, it will be passed through to AWS Security Token Service with the appropriate role for the token.
This is a public API. You do not need any credentials to call this API.
Generates (or retrieves) a Cognito ID.
Supplying multiple logins will create an implicit linked account.

Gets an OpenID token, using a known Cognito ID.
This known Cognito ID is returned by
GetId
. You can optionally add additional logins for the identity.
Supplying multiple logins creates an implicit link.
The OpenID token is valid for 10 minutes.

get_open_id_token_for_developer_identity(client, input, options \\ [])
View SourceRegisters (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.
Use GetPrincipalTagAttributeMap
to list all mappings between PrincipalTags
and user attributes.
Lists the identities in an identity pool.
You must use AWS Developer credentials to call this API.
Lists all of the Cognito identity pools registered for your account.
You must use AWS Developer credentials to call this API.
Lists the tags that are assigned to an Amazon Cognito identity pool.
A tag is a label that you can apply to identity pools to categorize and manage them in different ways, such as by purpose, owner, environment, or other criteria.
You can use this action up to 10 times per second, per account.
Retrieves the IdentityID
associated with a
DeveloperUserIdentifier
or the list of DeveloperUserIdentifier
values associated with an IdentityId
for an existing identity.
Either
IdentityID
or DeveloperUserIdentifier
must not be null. If you
supply only one of these values, the other value will be searched in the
database and
returned as a part of the response. If you supply both,
DeveloperUserIdentifier
will be matched against IdentityID
. If
the values are verified against the database, the response returns both values
and is the
same as the request. Otherwise a ResourceConflictException
is
thrown.
LookupDeveloperIdentity
is intended for low-throughput control plane
operations: for example, to enable customer service to locate an identity ID by
username.
If you are using it for higher-volume operations such as user authentication,
your requests
are likely to be throttled. GetOpenIdTokenForDeveloperIdentity
is a
better option for higher-volume operations for user authentication.
You must use AWS Developer credentials to call this API.
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.
The number of linked logins is limited to 20. So, the number of linked logins
for the
source user, SourceUserIdentifier
, and the destination user,
DestinationUserIdentifier
, together should not be larger than 20.
Otherwise, an exception will be thrown.
You must use AWS Developer credentials to call this API.
Sets the roles for an identity pool.
These roles are used when making calls to GetCredentialsForIdentity
action.
You must use AWS Developer credentials to call this API.
You can use this operation to use default (username and clientID) attribute or custom attribute mappings.
Assigns a set of tags to the specified Amazon Cognito identity pool.
A tag is a label that you can use to categorize and manage identity pools in different ways, such as by purpose, owner, environment, or other criteria.
Each tag consists of a key and value, both of which you define. A key is a
general
category for more specific values. For example, if you have two versions of an
identity
pool, one for testing and another for production, you might assign an
Environment
tag key to both identity pools. The value of this key might be
Test
for one identity pool and Production
for the
other.
Tags are useful for cost tracking and access control. You can activate your tags so that they appear on the Billing and Cost Management console, where you can track the costs associated with your identity pools. In an IAM policy, you can constrain permissions for identity pools based on specific tags or tag values.
You can use this action up to 5 times per second, per account. An identity pool can have as many as 50 tags.
Unlinks a DeveloperUserIdentifier
from an existing identity.
Unlinked developer users will be considered new identities next time they are seen. If, for a given Cognito identity, you remove all federated identities as well as the developer user identifier, the Cognito identity becomes inaccessible.
You must use AWS Developer credentials to call this API.
Unlinks a federated identity from an existing account.
Unlinked logins will be considered new identities next time they are seen. Removing the last linked login will make this identity inaccessible.
