I just did updates on my home cloud, and among those updates was a new version of bitwarden_rs. Bitwarden is a quite popular open source password management solution. I use it for quite some time already. Until some months ago, I used the hosted version, for which I even paid a few bucks to get premium features and support the developer behind the project.
But Bitwarden is open source and it’s possible to host your own Bitwarden server instance, which you can than use with the mobile apps, browser extensions and other client implementations.
