Returns a set of temporary security credentials for users who have been
authenticated via a SAML authentication response. This operation
provides a mechanism for tying an enterprise identity store or directory
to role-based Amazon Web Services access without user-specific
credentials or configuration. For a comparison of AssumeRoleWithSAML
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.
The temporary security credentials returned by this operation 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 services.
Session Duration
By default, the temporary security credentials created by
AssumeRoleWithSAML
last for one hour. However, you can use the
optional DurationSeconds
parameter to specify the duration of your
session. Your role session lasts for the duration that you specify, or
until the time specified in the SAML authentication response's
SessionNotOnOrAfter
value, whichever is shorter. You can provide a
DurationSeconds
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.
Role chaining
limits your CLI or Amazon Web Services API role session to a maximum of
one hour. When you use the AssumeRole
API operation to assume a role,
you can specify the duration of your role session with the
DurationSeconds
parameter. You can specify a parameter value of up to
43200 seconds (12 hours), depending on the maximum session duration
setting for your role. However, if you assume a role using role chaining
and provide a DurationSeconds
parameter value greater than one hour,
the operation fails.
Permissions
The temporary security credentials created by AssumeRoleWithSAML
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.
Calling AssumeRoleWithSAML
does not require the use of Amazon Web
Services security credentials. The identity of the caller is validated
by using keys in the metadata document that is uploaded for the SAML
provider entity for your identity provider.
Calling AssumeRoleWithSAML
can result in an entry in your CloudTrail
logs. The entry includes the value in the NameID
element of the SAML
assertion. We recommend that you use a NameIDType
that is not
associated with any personally identifiable information (PII). For
example, you could instead use the persistent identifier
(urn:oasis:names:tc:SAML:2.0:nameid-format:persistent
).
Tags
(Optional) You can configure your IdP to pass attributes into your SAML assertion 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, session tags override the role's tags 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.
SAML Configuration
Before your application can call AssumeRoleWithSAML
, you must
configure your SAML identity provider (IdP) to issue the claims required
by Amazon Web Services. Additionally, you must use Identity and Access
Management (IAM) to create a SAML provider entity in your Amazon Web
Services account that represents your identity provider. You must also
create an IAM role that specifies this SAML provider in its trust
policy.
For more information, see the following resources:
- About SAML 2.0-based Federation in the IAM User Guide.
- Creating SAML Identity Providers in the IAM User Guide.
- Configuring a Relying Party and Claims in the IAM User Guide.

Create a value of AssumeRoleWithSAML
with all optional fields omitted.
Use generic-lens or optics to modify other optional fields.
The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:policyArns:AssumeRoleWithSAML'
, assumeRoleWithSAML_policyArns
- The Amazon Resource Names (ARNs) of the IAM managed policies that you
want to use as managed session policies. The policies must exist in the
same account as the role.
This parameter is optional. You can provide up to 10 managed policy ARNs. However, the plaintext that you use for both inline and managed session policies can't exceed 2,048 characters. For more information about ARNs, see Amazon Resource Names (ARNs) and Amazon Web Services Service Namespaces in the Amazon Web Services General Reference.
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.
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.
$sel:durationSeconds:AssumeRoleWithSAML'
, assumeRoleWithSAML_durationSeconds
- The duration, in seconds, of the role session. Your role session lasts
for the duration that you specify for the DurationSeconds
parameter,
or until the time specified in the SAML authentication response's
SessionNotOnOrAfter
value, whichever is shorter. You can provide a
DurationSeconds
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. If you specify a value higher than this
setting, the operation fails. For example, if you specify a session
duration of 12 hours, but your administrator set the maximum session
duration to 6 hours, your operation fails. 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.
By default, the value is set to 3600
seconds.
The DurationSeconds
parameter is separate from the duration of a
console session that you might request using the returned credentials.
The request to the federation endpoint for a console sign-in token takes
a SessionDuration
parameter that specifies the maximum length of the
console session. For more information, see
Creating a URL that Enables Federated Users to Access the Management Console
in the IAM User Guide.
$sel:policy:AssumeRoleWithSAML'
, assumeRoleWithSAML_policy
- An IAM policy in JSON format that you want to use as an inline session
policy.
This parameter is optional. 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.
The plaintext that you use for both inline and managed session policies can't exceed 2,048 characters. The JSON policy characters can be any ASCII character from the space character to the end of the valid character list (\u0020 through \u00FF). It can also include the tab (\u0009), linefeed (\u000A), and carriage return (\u000D) characters.
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.
$sel:roleArn:AssumeRoleWithSAML'
, assumeRoleWithSAML_roleArn
- The Amazon Resource Name (ARN) of the role that the caller is assuming.
$sel:principalArn:AssumeRoleWithSAML'
, assumeRoleWithSAML_principalArn
- The Amazon Resource Name (ARN) of the SAML provider in IAM that
describes the IdP.
$sel:sAMLAssertion:AssumeRoleWithSAML'
, assumeRoleWithSAML_sAMLAssertion
- The base64 encoded SAML authentication response provided by the IdP.

newAssumeRoleWithSAMLResponse Source #
Create a value of AssumeRoleWithSAMLResponse
with all optional fields omitted.
Use generic-lens or optics to modify other optional fields.
The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:subject:AssumeRoleWithSAMLResponse'
, assumeRoleWithSAMLResponse_subject
- The value of the NameID
element in the Subject
element of the SAML
assertion.
$sel:audience:AssumeRoleWithSAMLResponse'
, assumeRoleWithSAMLResponse_audience
- The value of the Recipient
attribute of the SubjectConfirmationData
element of the SAML assertion.
$sel:packedPolicySize:AssumeRoleWithSAMLResponse'
, assumeRoleWithSAMLResponse_packedPolicySize
- A percentage value that indicates the packed size of the session
policies and session tags combined passed in the request. The request
fails if the packed size is greater than 100 percent, which means the
policies and tags exceeded the allowed space.
$sel:credentials:AssumeRoleWithSAMLResponse'
, assumeRoleWithSAMLResponse_credentials
- The temporary security credentials, which include an access key ID, a
secret access key, and a security (or session) token.
The size of the security token that STS API operations return is not fixed. We strongly recommend that you make no assumptions about the maximum size.
$sel:subjectType:AssumeRoleWithSAMLResponse'
, assumeRoleWithSAMLResponse_subjectType
- The format of the name ID, as defined by the Format
attribute in the
NameID
element of the SAML assertion. Typical examples of the format
are transient
or persistent
.
If the format includes the prefix
urn:oasis:names:tc:SAML:2.0:nameid-format
, that prefix is removed. For
example, urn:oasis:names:tc:SAML:2.0:nameid-format:transient
is
returned as transient
. If the format includes any other prefix, the
format is returned with no modifications.
$sel:nameQualifier:AssumeRoleWithSAMLResponse'
, assumeRoleWithSAMLResponse_nameQualifier
- A hash value based on the concatenation of the following:
- The
Issuer
response value. - The Amazon Web Services account ID.
- The friendly name (the last part of the ARN) of the SAML provider in IAM.
The combination of NameQualifier
and Subject
can be used to uniquely
identify a federated user.

- The identifiers for the temporary security credentials that the
operation returns.
$sel:sourceIdentity:AssumeRoleWithSAMLResponse'
, assumeRoleWithSAMLResponse_sourceIdentity
- The value in the SourceIdentity
attribute in the SAML assertion.
You can require users to set a source identity value when they assume a
role. You do this by using the sts:SourceIdentity
condition key in a
role trust policy. That way, actions that are taken with the role are
associated with that user. After the source identity is set, the value
cannot be changed. It is present in the request for all actions that are
taken by the role and persists across
chained role
sessions. You can configure your SAML identity provider to use an
attribute associated with your users, like user name or email, as the
source identity when calling AssumeRoleWithSAML
. You do this by adding
an attribute to the SAML assertion. For more information about using
source identity, see
Monitor and control actions taken with assumed roles
in the IAM User Guide.
The regex used to validate this parameter is a string of characters consisting of upper- and lower-case alphanumeric characters with no spaces. You can also include underscores or any of the following characters: =,.@-
$sel:issuer:AssumeRoleWithSAMLResponse'
, assumeRoleWithSAMLResponse_issuer
- The value of the Issuer
element of the SAML assertion.
$sel:httpStatus:AssumeRoleWithSAMLResponse'
, assumeRoleWithSAMLResponse_httpStatus
- The response's http status code.
