My almost 70 years old dad uses Pass for iOS in his everyday life. He does not have a clue about what's going on under the hood (gpg, git, my instance of gitea where it pushes to, me being able to intervene or fix stuff from somewhere else than his phone, etc.), but thats fine for both of us. He even complained, when I suggested to try Nextcloud Passwords because he might understand better what's going on there. So I guess in terms of UX this is a positive example.
