AWS SSO CLI is a secure replacement for using the aws configure sso wizard with a focus on security and ease of use for organizations with many AWS Accounts and/or users with many IAM Roles to assume. It shares a lot in common with aws-vault, but is more focused on the AWS SSO use case instead of static API credentials. Check out this page for more information on how these two tools compare.

AWS SSO CLI requires your AWS account(s) to be setup with AWS SSO! If your organization is using the older SAML integration (typically you will have multiple tiles in OneLogin/Okta) then this won't work for you.

In general, I do feature development in feature branches and then merge to the main branch when that feature is stable. I also tend to try to include any documentation changes in those pull requests. Once a release is ready, I tag the tip of main and do the release.

What that means is that the documentation you see here (tip of main) may include features that are not in the latest release. To view the docs for your release, please use the branch selector near the top of this page to choose the tag of the version of AWS SSO CLI that you are using.

AWS SSO CLI makes it easy to manage your shell environment variables allowing you to access the AWS API & web console using CLI tools. Unlike the official AWS tooling, the aws-sso command does not require manually creating named profiles in your ~/.aws/config (or anywhere else for that matter) for each and every role you wish to assume and use.

aws-sso focuses on making it easy to select a role via CLI arguments or via an interactive auto-complete experience with automatic and user-defined metadata (tags) and exports the necessary AWS STS Token credentials to your shell environment in a variety of ways.

As part of the goal of improving the end-user experience with AWS SSO, it also supports using multiple AWS Web Console sessions and many other quality of life improvements!

• Enhanced security over stock AWS tooling
• Auto-discover your AWS SSO roles and manage your ~/.aws/config file
• Support selecting an IAM role via $AWS_PROFILE, CLI (with auto-completion) or interactive search
• Ability to select roles based on user-defined and auto-discovered tags
• Support for multiple active AWS Console sessions
• Guided setup to help you configure aws-sso the first time you run
• Advanced configuration available to adjust colors and generate named profiles via templates
• Easily see how much longer your STS credentials are valid for
• Written in GoLang, so only need to install a single binary (no dependencies)
• Supports Linux, MacOS, and Windows

Here's a quick demo showing how to select a role to assume in interactive mode and then run commands in that context (by default it starts a new shell):

aws-sso also allows you to open the AWS Console in your browser for a given AWS SSO role:

Please note their is also a Security Policy.

Unlike the official AWS cli tooling, all authentication tokens and credentials used for accessing AWS and your SSO provider are encrypted on disk using your choice of secure storage solution. All encryption is handled by the 99designs/keyring library which is also used by aws-vault.

Credentials encrypted by aws-sso and not via the standard AWS CLI tool:

• AWS SSO ClientID/ClientSecret -- ~/.aws/sso/cache/botocore-client-id-<region>.json
• AWS SSO AccessToken -- ~/.aws/sso/cache/<random>.json
• AWS Profile Access Credentials -- ~/.aws/cli/cache/<random>.json

As you can see, not only does the standard AWS CLI tool expose the temporary AWS access credentials to your IAM roles, but more importantly the SSO AccessToken which can be used to fetch IAM credentials for any role you have been granted access!

• Contents of user defined ~/.aws-sso/config.yaml
• Metadata associated with the AWS Roles fetched via AWS SSO in ~/.aws-sso/cache.json
  • Email address tied to the account (root user)
  • AWS Account Alias
  • AWS Role ARN
