Struct aws_sdk_sts::client::fluent_builders::GetSessionToken

pub struct GetSessionToken { /* private fields */ }

Fluent builder constructing a request to GetSessionToken.

Returns a set of temporary credentials for an Amazon Web Services 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 Amazon Web Services API operations 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 API operations 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 API operations that produce temporary credentials, see Requesting Temporary Security Credentials and Comparing the Amazon Web Services STS API operations in the IAM User Guide.

No permissions are required for users to perform this operation. The purpose of the sts:GetSessionToken operation is to authenticate the user using MFA. You cannot use policies to control authentication operations. For more information, see Permissions for GetSessionToken in the IAM User Guide.

Session Duration

The GetSessionToken operation must be called by using the long-term Amazon Web Services security credentials of the Amazon Web Services account root user or an IAM user. Credentials that are created by IAM users are valid for the duration that you specify. This duration can range from 900 seconds (15 minutes) up to a maximum of 129,600 seconds (36 hours), with a default of 43,200 seconds (12 hours). Credentials based on account credentials can range from 900 seconds (15 minutes) up to 3,600 seconds (1 hour), with a default of 1 hour.

Permissions

The temporary security credentials created by GetSessionToken can be used to make API calls to any Amazon Web Services service with the following exceptions:

• You cannot call any IAM API operations 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 Amazon Web Services account root user 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 Amazon Web Services.

The credentials that are returned by GetSessionToken are based on permissions associated with the user whose credentials were used to call the operation. If GetSessionToken is called using Amazon Web Services account root user credentials, the temporary credentials have root user 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.

Implementations

impl GetSessionToken

pub async fn customize( self ) -> Result<CustomizableOperation<GetSessionToken, AwsResponseRetryClassifier>, SdkError<GetSessionTokenError>>

Consume this builder, creating a customizable operation that can be modified before being sent. The operation’s inner http::Request can be modified as well.

pub async fn send( self ) -> Result<GetSessionTokenOutput, SdkError<GetSessionTokenError>>

Sends the request and returns the response.

If an error occurs, an SdkError will be returned with additional details that can be matched against.

By default, any retryable failures will be retried twice. Retry behavior is configurable with the RetryConfig, which can be set when configuring the client.

pub fn duration_seconds(self, input: i32) -> Self

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

pub fn set_duration_seconds(self, input: Option<i32>) -> Self

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

pub fn serial_number(self, input: impl Into<String>) -> Self

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 Amazon Web Services Management Console and viewing the user's security credentials.

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: =,.@:/-

pub fn set_serial_number(self, input: Option<String>) -> Self

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).

pub fn token_code(self, input: impl Into<String>) -> Self

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, the user must provide a code when requesting a set of temporary security credentials. A user who fails to provide the code receives 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.

pub fn set_token_code(self, input: Option<String>) -> Self

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, the user must provide a code when requesting a set of temporary security credentials. A user who fails to provide the code receives 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.
