Lost the device with your passkey?
Two ways back in. Neither signs you in by itself — each sets up a new passkey on the device you're holding now.
Use a recovery code
The code is used up and every passkey on the account is removed, so a lost device stops being trusted.
No codes to hand?
If you signed up on this site, we can email you a new set-up link instead. Your existing passkeys keep working until you remove them from your account.
