I Use KeePassXC[0] on the desktop and is really great. It is open-source; not an Electron app, it is written in C++[1]; there are browser plugins to auto-fill user/password/TOTP codes; it is local-first: not tied to any cloud vendors and you can easily sync the database file via any cloud system if you want; there is an Android app that can use the same database.
