* other API operations that produce temporary credentials, see Requesting
* Temporary Security Credentials and Comparing
* the STS API operations in the IAM User Guide.
The temporary * security credentials returned by this API consist of an access key ID, a secret * access key, and a security token. Applications can use these temporary security * credentials to sign calls to Amazon Web Services service API operations.
* Session Duration
By default, the temporary security credentials
* created by AssumeRoleWithWebIdentity
last for one hour. However,
* you can use the optional DurationSeconds
parameter to specify the
* duration of your session. You can provide a value from 900 seconds (15 minutes)
* up to the maximum session duration setting for the role. This setting can have a
* value from 1 hour to 12 hours. To learn how to view the maximum value for your
* role, see View
* the Maximum Session Duration Setting for a Role in the IAM User
* Guide. The maximum session duration limit applies when you use the
* AssumeRole*
API operations or the assume-role*
CLI
* commands. However the limit does not apply when you use those operations to
* create a console URL. For more information, see Using
* IAM Roles in the IAM User Guide.
Permissions
*The temporary security credentials created by
* AssumeRoleWithWebIdentity
can be used to make API calls to any
* Amazon Web Services service with the following exception: you cannot call the
* STS GetFederationToken
or GetSessionToken
API
* operations.
(Optional) You can pass inline or managed session * policies 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. Passing policies to * this operation returns new temporary credentials. The resulting session's * permissions are the intersection of the role's identity-based policy and the * session policies. You can use the role's temporary credentials in subsequent * Amazon Web Services API calls to access resources in the account that owns the * role. You cannot use session policies to grant more permissions than those * allowed by the identity-based policy of the role that is being assumed. For more * information, see Session * Policies in the IAM User Guide.
Tags
*(Optional) You can configure your IdP to pass attributes into your web * identity token as session tags. Each session tag consists of a key name and an * associated value. For more information about session tags, see Passing * Session Tags in STS in the IAM User Guide.
You can pass up to * 50 session tags. The plaintext session tag keys can’t exceed 128 characters and * the values can’t exceed 256 characters. For these and additional limits, see IAM * and STS Character Limits in the IAM User Guide.
An
* Amazon Web Services conversion compresses the passed session policies and
* session tags into a packed binary format that has a separate limit. Your request
* can fail for this limit even if your plaintext meets the other requirements. The
* PackedPolicySize
response element indicates by percentage how close
* the policies and tags for your request are to the upper size limit.
You can pass a session tag with the same key as a tag that is attached to the * role. When you do, the session tag overrides the role tag with the same key.
*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.
You can set the session tags as transitive. Transitive tags * persist during role chaining. For more information, see Chaining * Roles with Session Tags in the IAM User Guide.
* Identities
Before your application can call
* AssumeRoleWithWebIdentity
, you must have an identity token from a
* supported identity provider and create a role that the application can assume.
* The role that your application assumes must trust the identity provider that is
* associated with the identity token. In other words, the identity provider must
* be specified in the role's trust policy.
Calling
* AssumeRoleWithWebIdentity
can result in an entry in your CloudTrail
* logs. The entry includes the Subject
* of the provided web identity token. We recommend that you avoid using any
* personally identifiable information (PII) in this field. For example, you could
* instead use a GUID or a pairwise identifier, as suggested
* in the OIDC specification.

To * learn more about Amazon Cognito, see Amazon * Cognito Overview in Amazon Web Services SDK for Android Developer * Guide and Amazon * Cognito Overview in the Amazon Web Services SDK for iOS Developer * Guide.
Calling AssumeRoleWithWebIdentity
does
* not require the use of Amazon Web Services security credentials. Therefore, you
* can distribute an application (for example, on mobile devices) that requests
* temporary security credentials without including long-term Amazon Web Services
* credentials in the application. You also don't need to deploy server-based proxy
* services that use long-term Amazon Web Services credentials. Instead, the
* identity of the caller is validated by using a token from the web identity
* provider. For a comparison of AssumeRoleWithWebIdentity
with the

When you pass
* an access key ID to this operation, it returns the ID of the Amazon Web Services
* account to which the keys belong. Access key IDs beginning with
* AKIA
are long-term credentials for an IAM user or the Amazon Web

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
. 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.

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 plain text 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.
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.
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).

You can use the temporary credentials created by
* GetFederationToken
in any Amazon Web Services service except the

You cannot call any IAM operations using the CLI or * the Amazon Web Services API.
You cannot call any STS

.
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.
