Is it possible to turn off showing the information about preferred username in sign-in window? By passing some parameter during Azure log-in request? I have configured application in App registrations / Enterprise applications in Entra ID. Here preferred username is the generated name with the "guest" keyword inside. It can be confusing for our users. We want to show only theirs real email address.User's image

    Hi @Przemysław Szymura

    Thank you for posting this in Microsoft Q&A.I understand you want to hide the UPN of the user when signing the azure login window.

    Unfortunately, there isn't a way to remove or hide the preferred username (which typically includes the "guest" keyword) from being displayed during the sign-in process in Entra ID through parameters passed during the login request. As of now only users can use Email or UPN to sign-in to Azure/Microsoft Entra ID.

    Hope this helps. Do let us know if you any further queries.

    Thanks,

    Navya.
