Passkey
A credential stored on your device that signs you in without a password.
Built on WebAuthn, a passkey is a key pair: the private half never leaves the device and is unlocked by a fingerprint, a face or a PIN. It cannot be phished, because the browser refuses to use it on the wrong domain, and it cannot be reused elsewhere because each site gets its own.
It is tied to the domain it was made for — a passkey for one site is meaningless on another, by design.
Where Naven stands
Naven supports passkeys, set up from Settings. They are the fastest way back in and the only credential here that cannot be phished.
