AWS CLI Federation: Secure, Short-Lived Access Without Static Keys

The login prompt kept timing out, and nothing was working the way it should.

That’s the moment you realize: AWS CLI federation isn’t just a convenience. It’s the only sane way to handle secure, temporary, role-based access without drowning in static credentials.

With AWS Command Line Interface (CLI) federation, you skip long-lived keys. You link your workforce identity provider—like Okta, Azure AD, or AWS SSO—directly to the CLI so developers and systems use secure, short-lived tokens. This means faster onboarding, cleaner offboarding, and less risk from leaked keys.

Why AWS CLI Federation Matters

Static access keys expire only when you remember to rotate them. That creates risk. Federation replaces them with ephemeral credentials issued via an identity provider (IdP). The CLI uses SAML or OIDC to request these credentials on demand. Logging in becomes a single command instead of a copy-paste ritual.

How AWS CLI Federation Works

The process is simple. Configure your IdP in AWS IAM Identity Center or IAM roles with trust policies for your provider. Update your AWS CLI config to include the sso_start_url, sso_region, sso_account_id, and sso_role_name parameters—or if using OIDC/SAML federation directly, store your profile with the proper credential_process command. Once configured, aws sso login (or your federation login command) opens a browser, authenticates through your IdP, and returns short-lived credentials for CLI use. No static keys on disk. No more endless aws configure.

Security Advantages

• No long-term keys: Credentials vanish when the session ends.
• Centralized access control: Use your IdP to manage user and group roles in one place.
• Faster revocation: Kill access instantly through the IdP without touching AWS accounts.

Best Practices

• Enforce MFA on all IdP logins.
• Keep session durations short, but long enough for work to get done.
• Test role policies regularly with the CLI to ensure permissions are scoped.
• Automate profile creation for new users to remove setup friction.

Common Pitfalls

• Neglecting to sync user attributes between IdP and AWS can break access.
• Misconfigured trust relationships can cause permission errors.
• Forgetting to install the right AWS CLI version—federation features require v2.

Getting Started Fast

If you’re still passing static keys to developers, this is your moment to cut them out completely. Configure CLI federation once and watch onboarding time drop. You can see a working AWS CLI federation setup live in minutes—no guesswork, no waiting—by trying it with hoop.dev.
