I can log in to Concur mobile app and when i go to settings and change login to facetime and then logout when I try to log back in it still asks me for my password and username. I checked the settings on my phone with respect to Concur and it shows is has access to my camera. I have an iphone 10 running the latest ios.
@jacala1 First off, I believe you are talking about Face ID, not FaceTime. :-)
I found out that the Face ID option is to re-authenticate users that have been timed out of the app.
I hope this helps.
