Bitwarden if you want a cloud service

KeePass or KeePassXC if you want to control your own data and use something like Syncthing to sync

There is vaultwarden which is self hosted version of bitwarden.

[precurse]

Yep! I run it myself and it works fantastic.

And my contingency plan if I can no longer self host, is export from one of my devices and import into the cloud version of Bitwarden. I don't see myself needing to do that, but you never know.
