I have Norton LifeLock Ultimate Plus. Today I tried to add a YubiKey as an MFA option. The first key was fine, but when I added backup keys, there was no different treatment of the keys - namely the ability to name or otherwise identify them. Although I was able to add all 3 keys, when I logged out and back in and tried to use a key to authenticate, it gave me three key options in a manner that made it appear they were mutually exclusive, and since I was unable to name the keys when I registered them, I was unable to figure out which was which - and I didn't want to use trial and error for fear of being locked out.
Am I doing something wrong?
