What are the best practices for managing authorization in AWS?

I'm looking for guidance on the best practices for managing authorization in AWS. Specifically, I'm wondering about the different methods to authenticate and authorize users or roles, especially in terms of integrating these processes into a codebase. What approaches should I consider, and is using a key pair authentication method still recommended?

As someone new to AWS, I've found that key pairs aren't the best way to authenticate users, especially for applications. Instead, consider using SAML federation; it's a more secure option for managing user identities and access.

When it comes to authorization in AWS, IAM (Identity and Access Management) is definitely the go-to solution. However, the best approach can depend on your specific needs. For individual accounts, IAM users combined with hardware-based MFA like FIDO2 is a strong choice. If you’re managing multiple accounts, using AWS IAM Identity Center linked to your company’s identity provider can simplify things and help manage MFA effectively.

For any kind of secure setup, avoiding key pairs is advisable. Look into alternatives like using SAML or even OpenID Connect for better integration with modern applications.
