set-security-token-service-preferences¶

Description¶

Sets the specified version of the global endpoint token as the token version used for the AWS account.

By default, AWS Security Token Service (STS) is available as a global service, and all STS requests go to a single endpoint at https://sts.amazonaws.com . AWS recommends using Regional STS endpoints to reduce latency, build in redundancy, and increase session token availability. For information about Regional endpoints for STS, see AWS Regions and Endpoints in the AWS General Reference .

If you make an STS call to the global endpoint, the resulting session tokens might be valid in some Regions but not others. It depends on the version that is set in this operation. Version 1 tokens are valid only in AWS Regions that are available by default. These tokens do not work in manually enabled Regions, such as Asia Pacific (Hong Kong). Version 2 tokens are valid in all Regions. However, version 2 tokens are longer and might affect systems where you temporarily store tokens. For information, see Activating and Deactivating STS in an AWS Region in the IAM User Guide .

To view the current session token version, see the GlobalEndpointTokenVersion entry in the response of the GetAccountSummary operation.

Synopsis¶

  set-security-token-service-preferences
--global-endpoint-token-version <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options¶

--global-endpoint-token-version (string)

The version of the global endpoint token. Version 1 tokens are valid only in AWS Regions that are available by default. These tokens do not work in manually enabled Regions, such as Asia Pacific (Hong Kong). Version 2 tokens are valid in all Regions. However, version 2 tokens are longer and might affect systems where you temporarily store tokens.

For information, see Activating and Deactivating STS in an AWS Region in the IAM User Guide .

Possible values:

v1Token

v2Token

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Examples¶

To set the global endpoint token version

The following set-security-token-service-preferences example configures Amazon STS to use version 2 tokens when you authenticate against the global endpoint.

aws iam set-security-token-service-preferences \
    --global-endpoint-token-version v2Token

This command produces no output.

Output¶

None
