QtPass is a multi-platform GUI for pass, the standard Unix password manager.
Each password lives in its own GnuPG-encrypted file in ~/.password-store, so
QtPass shares the store with the pass command line and with every other pass
client, and keeps history and synchronisation in git.

QtPass can drive the pass script or talk to gpg and git directly, supports
multi-key and multi-recipient encryption with per-folder recipients, OpenPGP
smartcards and other external tokens, generates passwords with pwgen or its
own generator, shows QR codes for entries, and generates TOTP one-time codes
from otpauth:// entries without extra tools.
