A significant advantage is that unlike access keys and secret keys that require regular changes every 30-90 days based on organizational policy, AWS Identity and Access Management roles, once set up, do not require periodic changes.
AWS Identity and Access Management offers powerful security features like standard access policies, roles, and MFA for enhanced monitoring and privilege management. It allows organizing users into groups and defining policies. Although beneficial in managing security, it could improve with a user-friendly GUI and clearer documentation. Better integration with systems and stronger unauthorized access prevention is needed. The ability to create multiple keys for a user enhances flexibility.
