I tried TransferChain Pass for personal use. Passwords are stored very securely thanks to advanced client-side and end-to-end encryption, and blockchain authentication enhances security. Autofill in the browser works well, but sometimes there are delays with the extension. The interface is simple, but the password editing and organization features could be more user-friendly. Unfortunately, there is no full-fledged Android app yet, and the mobile version is limited in functionality, which reduces its usability on smartphones. For one person, it's still a good option if security is important and you're willing to put up with some limitations on mobile devices.
