Returns a set of temporary credentials for an AWS account or IAM user.
The credentials consist of an access key ID, a secret access key, and a
security token. Typically, you use GetSessionToken
if you want to use
MFA to protect programmatic calls to specific AWS APIs like Amazon EC2
StopInstances
. MFA-enabled IAM users would need to call
GetSessionToken
and submit an MFA code that is associated with their
MFA device. Using the temporary security credentials that are returned
from the call, IAM users can then make programmatic calls to APIs that
require MFA authentication. If you do not supply a correct MFA code,
then the API returns an access denied error. For a comparison of
GetSessionToken
with the other APIs that produce temporary
credentials, see Requesting Temporary Security Credentials
and Comparing the AWS STS APIs
in the IAM User Guide.
sts_get_session_token(DurationSeconds, SerialNumber, TokenCode)
The duration, in seconds, that the credentials should remain valid. Acceptable durations for IAM user sessions range from 900 seconds (15 minutes) to 129600 seconds (36 hours), with 43200 seconds (12 hours) as the default. Sessions for AWS account owners are restricted to a maximum of 3600 seconds (one hour). If the duration is longer than one hour, the session for AWS account owners defaults to one hour.
The identification number of the MFA device that is associated with the
IAM user who is making the GetSessionToken
call. Specify this value if
the IAM user has a policy that requires MFA authentication. The value is
either the serial number for a hardware device (such as GAHT12345678
)
or an Amazon Resource Name (ARN) for a virtual device (such as
arn:aws:iam::123456789012:mfa/user
). You can find the device for an
IAM user by going to the AWS Management Console and viewing the user's
security credentials.
The regex used to validated 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: =,.@:/-
The value provided by the MFA device, if MFA is required. If any policy requires the IAM user to submit an MFA code, specify this value. If MFA authentication is required, and the user does not provide a code when requesting a set of temporary security credentials, the user will receive an "access denied" response when requesting resources that require MFA authentication.
The format for this parameter, as described by its regex pattern, is a sequence of six numeric digits.
svc$get_session_token( DurationSeconds = 123, SerialNumber = "string", TokenCode = "string" )
The GetSessionToken
action must be called by using the long-term AWS
security credentials of the AWS account or an IAM user. Credentials that
are created by IAM users are valid for the duration that you specify,
from 900 seconds (15 minutes) up to a maximum of 129600 seconds (36
hours), with a default of 43200 seconds (12 hours); credentials that are
created by using account credentials can range from 900 seconds (15
minutes) up to a maximum of 3600 seconds (1 hour), with a default of 1
hour.
The temporary security credentials created by GetSessionToken
can be
used to make API calls to any AWS service with the following exceptions:
You cannot call any IAM APIs unless MFA authentication information is included in the request.
You cannot call any STS API except AssumeRole
or
GetCallerIdentity
.
We recommend that you do not call GetSessionToken
with root account
credentials. Instead, follow our best practices
by creating one or more IAM users, giving them the necessary
permissions, and using IAM users for everyday interaction with AWS.
The permissions associated with the temporary security credentials
returned by GetSessionToken
are based on the permissions associated
with account or IAM user whose credentials are used to call the action.
If GetSessionToken
is called using root account credentials, the
temporary credentials have root account permissions. Similarly, if
GetSessionToken
is called using the credentials of an IAM user, the
temporary credentials have the same permissions as the IAM user.
For more information about using GetSessionToken
to create temporary
credentials, go to Temporary Credentials for Users in Untrusted Environments
in the IAM User Guide.
