Yes, through your device's built-in password manager. V5's login page is marked as a standard username and password field, so Safari/Chrome's iCloud Keychain or Google Password Manager will recognize it: when you first log in with a password, the browser will ask "Save password?", and after you save it, the next time you visit the login page, you can press your fingerprint or scan your face and it will automatically fill in and log you in. The password you actually send is still yours; the device just manages it for you.
For people signing in with Google or Microsoft accounts, fingerprint/face recognition is completed on Google's or Microsoft's end. If you've already set up a Passkey there, after clicking the Google/Microsoft button on Patisco's login page it will use that to verify you.
Passkey-based passwordless login for Patisco's own accounts (not going through Google/Microsoft) is not yet supported, but this feature is in our roadmap.
