Integrations and plugins exist, and for me, browser integration was easy to set up.

Yeah KeePass is great! I currently use KeePass2 on my Trisquel 7 machine. I use that app in conjunction with Deja Dup to back up my password database to S3. There's even an app on the fdroid store called KeePassDroid but I've yet to make it work. I think the version on the store hasn't been recently updated.

I use pass too and love it, but it is worth noting that the names of the passwords are not encrypted, meta data based on the names can be extracted. The naming scheme is fully up to you though, but if you don't want to expose meta data at all, I'd recommend keepass instead.

I also use Keepass[x]! The issue that I see people facing is that it isn't multi-device (it's an offline password manager). For me, that is the selling point though.
