AWS Command Line Interface adds PKCE-based authorization for single sign-on

The article discusses a new feature added to the AWS Command Line Interface (AWS CLI) v2 that supports OAuth 2.0 authorization code flows using the Proof Key for Code Exchange (PKCE) standard. This provides a simple and secure way to retrieve credentials for AWS CLI commands.

Specifically, the article covers:

• The AWS CLI is a tool for controlling multiple AWS services from the command line and automating them through scripts.
• AWS CLI v2 offers integration with AWS IAM Identity Center, the recommended service for managing workforce access to AWS applications and multiple AWS accounts.
• The authorization code flow with PKCE is the recommended best practice for accessing AWS resources from desktops and mobile devices with web browsers.
• It is now the default behavior when running the aws sso login or aws configure sso commands.
• More information and documentation links are provided for configuring IAM Identity Center authentication with the AWS CLI.
