I'm very much a fan of password-store on that list:

https://www.passwordstore.org/

Worst case scenario it's basically just a wrapper for GPG, so you can always get at the password if you have access to your GPG keyring.

I've also never had to directly install it on Linux, it seems to come pre-installed on most distros recently (I think it's a part of GNOME or something, even though I don't use that).
