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 standard policies and roles for security, enhancing control with group and individual policies. It restricts unauthorized console use and allows policy organization. Flexible permissions, wildcard use, and explicit conditions are provided. A graphical interface, temporary access, and enhanced user activity tracking could improve usability. Clarity in CLI options and allowing multiple access keys per user would better accommodate diverse needs.
