Unlike Bitwarden, has no passkey functionality and doesn't have login form integration. It's bad UI that you have to add trusted Autofill domains separately, when it could add a checkbox to each login entry's URL whether to trust the domain or not. The device connection is a little annoying, and lock on restart is a paid feature.

Achei OK. Só falta colocar em Português.

Best password manager ever, fast and secure, graphically well done.
