Passkeys
What a passkey is, adding one, and why having a second one is the whole point.
A passkey is a key your device keeps for you. Signing in means unlocking the device the way you already do — fingerprint, face, or the code that opens it. There is nothing to type and nothing to remember.
It is also not something that can be phished. There is no code to read out to someone on the phone and no password to enter on a lookalike page, because the key never leaves your device and only works on the real address.
Adding one
From Account. Your browser asks how you want to store it — the device itself, or your password manager — and that is the whole process.
ANVL names it after the device you registered it on. If that name will not mean anything to you in a year, rename it with the pencil on its row.
Have more than one
This is the part people skip, and it is the part that matters.
One passkey on one device means the device is your only way in. Add a second one — a phone as well as a laptop, or a password manager that syncs — and losing one stops being a problem.
Adding the second one takes about ten seconds and you do it once. Doing it after you lose the first is not an option, which is the whole difficulty.
Removing one
Also from Account, one per row. Remove a passkey when the device is gone, sold or replaced.
You cannot remove your last passkey, and having a password does not change that. So a device that carried your only passkey cannot simply be cleared from the list — add another passkey first, and then remove the old one.
