Returns a set of temporary security credentials (consisting of an access
key ID, a secret access key, and a security token) for a federated user.
A typical use is in a proxy application that gets temporary security
credentials on behalf of distributed applications inside a corporate
network. You must call the GetFederationToken
operation using the
long-term security credentials of an IAM user. As a result, this call is
appropriate in contexts where those credentials can be safely stored,
usually in a server-based application. For a comparison of
GetFederationToken
with the other API operations that produce
temporary credentials, see
Requesting Temporary Security Credentials
and
Comparing the STS API operations
in the IAM User Guide.
You can create a mobile-based or browser-based app that can authenticate
users using a web identity provider like Login with Amazon, Facebook,
Google, or an OpenID Connect-compatible identity provider. In this case,
we recommend that you use
Amazon Cognito or
AssumeRoleWithWebIdentity
. For more information, see
Federation Through a Web-based Identity Provider
in the IAM User Guide.
You can also call GetFederationToken
using the security credentials of
an Amazon Web Services account root user, but we do not recommend it.
Instead, we recommend that you create an IAM user for the purpose of the
proxy application. Then attach a policy to the IAM user that limits
federated users to only the actions and resources that they need to
access. For more information, see
IAM Best Practices
in the IAM User Guide.
Session duration
The temporary credentials are valid for the specified duration, from 900 seconds (15 minutes) up to a maximum of 129,600 seconds (36 hours). The default session duration is 43,200 seconds (12 hours). Temporary credentials that are obtained by using Amazon Web Services account root user credentials have a maximum duration of 3,600 seconds (1 hour).
Permissions
You can use the temporary credentials created by GetFederationToken
in
any Amazon Web Services service except the following:
- You cannot call any IAM operations using the CLI or the Amazon Web Services API.
- You cannot call any STS operations except
GetCallerIdentity
.
You must pass an inline or managed session policy to this operation. You can pass a single JSON policy document to use as an inline session policy. You can also specify up to 10 managed policies to use as managed session policies. The plaintext that you use for both inline and managed session policies can't exceed 2,048 characters.
Though the session policy parameters are optional, if you do not pass a
policy, then the resulting federated user session has no permissions.
When you pass session policies, the session permissions are the
intersection of the IAM user policies and the session policies that you
pass. This gives you a way to further restrict the permissions for a
federated user. You cannot use session policies to grant more
permissions than those that are defined in the permissions policy of the
IAM user. For more information, see
Session Policies
in the IAM User Guide. For information about using
GetFederationToken
to create temporary security credentials, see
GetFederationToken—Federation Through a Custom Identity Broker.
You can use the credentials to access a resource that has a
resource-based policy. If that policy specifically references the
federated user session in the Principal
element of the policy, the
session has the permissions allowed by the policy. These permissions are
granted in addition to the permissions granted by the session policies.
Tags
(Optional) You can pass tag key-value pairs to your session. These are called session tags. For more information about session tags, see Passing Session Tags in STS in the IAM User Guide.
You can create a mobile-based or browser-based app that can authenticate
users using a web identity provider like Login with Amazon, Facebook,
Google, or an OpenID Connect-compatible identity provider. In this case,
we recommend that you use
Amazon Cognito or
AssumeRoleWithWebIdentity

federated user session in the Principal

session has the permissions allowed by the policy. These permissions are
granted in addition to the permissions granted by the session policies.
Tags
(Optional) You can pass tag key-value pairs to your session. These are called session tags. For more information about session tags, see Passing Session Tags in STS in the IAM User Guide.
An administrator must grant you the permissions necessary to pass session tags. The administrator can also create granular permissions to allow you to pass only specific session tags. For more information, see Tutorial: Using Tags for Attribute-Based Access Control in the IAM User Guide.
Tag key–value pairs are not case sensitive, but case is preserved. This
means that you cannot have separate Department
and department
tag
keys. Assume that the user that you are federating has the
Department
=Marketing
tag and you pass the department
=engineering
session tag. Department
and department
are not saved as separate
tags, and the session tag passed in the request takes precedence over
the user tag.

Your request can fail for this limit even if your plaintext meets the

response element indicates by
percentage how close the policies and tags for your request are to the
upper size limit.
$sel:durationSeconds:GetFederationToken'

- The duration, in seconds, that the session should last. Acceptable
durations for federation sessions range from 900 seconds (15 minutes) to
129,600 seconds (36 hours), with 43,200 seconds (12 hours) as the
default. Sessions obtained using Amazon Web Services account root user
credentials are restricted to a maximum of 3,600 seconds (one hour). If
the specified duration is longer than one hour, the session obtained by
using root user credentials defaults to one hour.
