Azure SSO without @Domain?

Adam Pettit 0

I remember seeing somewhere that Microsoft is moving to allowing a feature in which the domain (@ecasd.us) is no longer necessary and users only need their PrincipalUserName (username). Anyone have a read on this and it's release?

The @domain portion is part of the userPrincipalName attribute

@Marcin Policht our ultimate goal is that our users no longer need to use their full email address to login, specifically our young students.

Entra ID must be able to identify the tenant/domain you are trying to authenticate against. Without you providing UPN or the domain name, how else would you expect that this is information is obtained by Entra ID?
