Authenticator Phone Sign-In for Office 365 Work Accounts?

New Contributor

I have the Microsoft Authenticator setup for both my personal Microsoft account and have been testing it with our new Office 365 work account that we just set up.


My personal account was setup with Phone sign-in where instead of a password it shows you a selection of 3 numbers, you chose the one that is shown on the login window, use your pin/fingerprint and it signs you in without a password.


My work one uses the traditional one where you enter your password and it then asks you to approve it on the mobile device.


I noticed that I could set up Phone Sign-In for my work account in the authenticator app, after doing so it seems as if nothing has changed. It still asks me for the password everywhere, and gives me the traditional approve/deny message in the app. 


Am I doing something wrong? I didn't see any setting that seemed to allow or deny the use of phone sign in inside the exchange/azure admin panel settings. My account is already set to enabled for multi factor (or it wouldn't be working at all) and I can't seem to find any other information about this.


This page seems to suggest it will work for "work or school accounts"

And i've done everything on the authenticator app side that it mentioned, but nothing has changed on the login side. Not inside the email web login or with logging into office apps, both work to prompt the newer phone sign-in when I use my personal credentials instead.

Same experience here. I'm not quite sure it's rolled out for everyone yet from a front end perspective. Everyone I've seen trying it has the exact same experience. Sets up fine, but the UI just isn't doing the whole new process of signing in when using the account tied to it.
