Hi,
Replaced my phone with one another identical one and restored my Authenticator app. Now in my security profile I have two authenticator apps registered, both with the same name (the phone model). Which one is the old one and which is the new? Want to remove the old one. Looking in the app, I can see the device name, but I can not change it. How to fix this?
