Web developer at King of CMS Consulting
Centralized access control has improved team collaboration but still needs a simpler onboarding
One of the best features AWS IAM Identity Center offers is the permission set, which is one of the best. Then there are the temporary credentials via SSO, the multi-account governance, and the centralized identity management. Those are good features that I believe assist developers, and another feature I can say is one of the best is the improved security with temporary credentials. The feature I find myself relying on the most day-to-day would be the centralized identity management and multi-account governance. It allows me to check what other developers are doing and since I am the admin, I can also revoke the access they have to the AWS accounts.

Consultant at Artifield
Offers strong identity unification but needs better customization
Microsoft Entra External ID can be improved with additional features, specifically customizable flexibility and a customizable user interface for the login dialog. Currently, the login dialog has very limited customization options, which only include font styles, colors, text messages, or brand icons. Last month, Entra ID introduced some customizable features in their login dialog, but this does not apply to Microsoft Entra External ID, indicating a significant gap between the two. In theory, Entra External ID can support many external identity providers where custom login dialogs could be integrated, potentially via SSO feature coordination, although I have not yet confirmed this. Hence, enhanced customizable login options and the ability to use attribute password logins are critical features that are required for Microsoft Entra External ID to gain dominance in the authentication market.
