RexiMemo supports WebAuthn passkeys on compatible secure browsers. Open Settings → Passkeys, choose a name for the passkey, and let your browser or operating system complete the registration.
Passkeys can use the authenticator your device provides, such as a platform biometric or screen-lock protected credential. RexiMemo keeps the public credential information needed to verify future sign-ins; your private passkey material stays with the authenticator.
If your browser or device does not support the required WebAuthn features, the registration control is unavailable and you can continue using your normal RexiMemo username and password.
