Beyond IAM access keys: Modern authentication approaches for AWS

The article discusses modern, secure alternatives to traditional AWS IAM access keys for various use cases, focusing on reducing security risks associated with long-term credentials.

• AWS CloudShell provides browser-based CLI access without local credential management
• AWS CLI v2 with IAM Identity Center offers centralized user management and MFA
• Modern IDEs like Visual Studio Code support secure authentication through IAM Identity Center
• AWS compute services and CI/CD pipelines should use IAM roles for temporary, rotated credentials
• External access can leverage IAM Roles Anywhere, OIDC integration, and third-party access methods

The key recommendation is to prefer temporary credentials, implement least privilege, and continuously update authentication methods to enhance security across AWS environments.
