Upass is a curses-based (more specifically urwid) interface for pass, the standard Unix password manager. It provides a simple, but powerful view of the password store and can copy passwords or extended information to the clipboard interactively.

pass is the standard unix password manager, to be found in the pass package.

There is another implementation of a curses interface, gopass.pw, but it is a complete reimplementation. In contrast, upass simply wraps the standard pass implementation.
