AZ AD B2C | How to block Mobile Sign in of a user ?

Hi,
I have tried the Block Sign in feature inside user details blade. But that seems to work only for emal sign in and not mobile sign in developed using custom policy in paswordless scenario.
Is there a way to do that using custom policy or by admin in the Azure Blades ?

Hi @AbhayChandramouli-2076 , are you trying to block a specific user? Or just generally according to a custom policy?

Hi @AbhayChandramouli-2076 , thank you for your question. The simplest way to block or remove a single user is by removing their account in the portal or PowerShell. You could also block their IP address, which is more complicated but there are a lot of good articles detailing how.

Conditional Access is a popular way to configure and detect risky sign-ins, and block them when necessary. The linked document details how you can block access from certain locations, for example.

Please let me know if you have any questions or if you have a specific use case I can help with!

Thank you,
James

Hi James,
What I am looking for is more of a temporary block. We have the block sign in checkbox in azure portal users blade, but that seems to work only for email and password and not for mobile and OTP.
