Laptop wasn’t running smooth anymore. Tried a bunch of stuff in Winxows, nothing helped. Formatted the drive, installed linux, ran buttery smooth for years until some graphics shit died. Did the same to a thinkpad back in 2018 or 19. Still up an running like a champ but the thing went crazy on the original windows it came with (2nd hand. I’m also cheap…)
There are keepass android apps like KeePassDX. You can have server sync with WebDav, but I don’t know about shared databases. Should work if you configure the WebDav server etc.
A friend of mine is a big fan of bitwarden but I have no Idea if that fits your requirement. Should have a webui tho.
