OpenKeychain and Password-store (paired with a yubikey) is the entire reason I use Android over iOS. I really wish there was hardware GPG key solution for the iphone.
Did you see it's missing a maintainer?
I agree, using gpg on yubikey for password encryption is ideal. My only problem with it is that nobody makes money, so who is maintaining it?
Capitalism continues to wow the masses
Don't get me wrong I would pay... But there is no attempt to make money from this.
Cause it works great and even supports TOTP and extra data, aside from passwords.
I've been using pass with a yubikey for the past year and a half and have been very happy with it. The ability to call out to the pass binary in personal scripts is a really handy feature that I didn't realize would be so useful until I started using it.
I already have this capability with password-store (pass), that works for Firefox, Chrome and Safari on destop and mobile.
