Ah, there is an Android app [1] which you sync the passwords to and it basically presents a list of all your websites. To use a password: tap on the website name, unlock your GPG key, and then see your password and put it in your phone's copy/paste buffer.
This is correct. Pass can only copy it in the paste buffer for 45s.
The command has a nice auto completion and search feature. And calling it without arguing give you a list of all the name of the key you have in a tree view.
I really enjoy using that little utility since I would say 4 or 5 years.
