How do I sign in with a passkey?

Settings › Security › Passkeys

A passkey signs you in with your face, fingerprint or a security key instead of a password. Add one in Settings › Security › Passkeys; the browser or phone does the rest. The sign-in page then offers Sign in with a passkey. You can keep several, name each one and remove any of them. Passkeys cannot be phished because they only work on this site.
