Hello,

I use "Get-MgUserAuthenticationMethod" to get all configured methods for each user.

However, as it turned out, this method shows "Microsoft Authenticator - Outlook Mobile" as "Microsoft Authenticator".

Unfortunately, I did not find other methods that would give more detailed information. However, I need to somehow identify users who have "Microsoft Authenticator - Outlook Mobile".

Perhaps you can suggest some other approach.

I have added a screenshot displaying information about authentication methods.

Thank you.

    You need to use the /beta endpoint and take a look at the clientAppName property, it will return a value of outlookMobile for any users that have Authenticator Lite/via Outlook.. Refer to the documentation for more details: https://learn.microsoft.com/en-us/graph/api/resources/microsoftauthenticatorauthenticationmethod?view=graph-rest-beta
