set-security-token-service-preferences¶

Description¶

Sets the specified version of the global endpoint token as the token version used for the Amazon Web Services account.

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

Options¶

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

The version of the global endpoint token. Version 1 tokens are valid only in Amazon Web Services 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 Amazon Web Services 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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

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.
