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.
