If you can't get in using your pin or passcode then I am afraid you will have to factory reset your phone.
Personal Device locked by authenticator
I had to install Intune and Authenticator to my personal phone so that I can use Microsoft teams on my personal cell phone. I couldn't get it set up right and now my personal phone is locked by it. I cannot open it. I don't have any pin. My work IT department can't do anything, and Microsoft doesn't have any phone in suppprt any longer. Is this now a 1500$ mistake where I have to buy a new phone? How do I reset the pin? When I sign in it says there are no devices associated with my account because I thought deleting the device would help, but it didn't I'm just stuck at nothing. Not to mention I need my phone to work because I need to sign on to my vpn to work my work computer. What do I do?
