I purchased an “NFC security key” and added it to my FIDO login. I have two questions: Can I delete the “admin” account and log in only with the key? Can I attach a second key to FIDO and log in with the second one if the first one is destroyed or lost?

misio you cannot delete the admin account, the NFC key would still need to be associated to an account ir order to perform the authentication, but you might want to use an extra complex password for that user to further protect.
Also, you should either use 2FA or the key, rather than the user/password alone. 😉

1) I do not believe so. What you are talking about, is 2FA (Two-Factor Authentication) and your new security key is just second factor, so if you still need first, you need an account and password to log in.

2) Yes, you can add several 2FA keys to one account, in fact I highly recommend this.

I don’t use 2fa because I log in with either an account or a key. I would like to leave only the key, but I don’t know if deleting the admin account is safe 🙂
