So I have an Azure Active Directory app registration for my Xamarin mobile app that allows a user to authenticate with AAD and do things like show their profile information. All is well.
What I am looking to do is force the user to re-authenticate with a fingerprint (if available) on-demand. Much like how the Outlook for Android app authenticates me all the time, asking for a fingerprint, how do I do that? Is this a feature or ADAL, MSAL, Microsoft Authenticator, or something else?
