Microsoft Authenticator Biometric

Question

Hi! This request is mainly for me. If it helps others GREAT! I'm having an issue with hackers. I need assistance with getting my Authenticator adjusted to more stricter access. When using the biometric option, there's an alternative option of using a pattern. This is not good. I need the 'use pattern' option to be removed and the alternative is nothing or phone number. For reasons I can't explain and being taken seriously, Pins, patterns, anything like that cannot, should not be an option. The keyboard lights up for every letter so pin is not an option, and when changing patterns, the first time is visible, which is also unacceptable. I am in a situation right now where lockdown of all information is important. These hackers have out-of-the-norm means of getting passwords, pins, etc.
