The Password Manager Daemon provides data to applications through a socket in the background.
If you're experiencing difficulties with password entry, ensure that gpg-agent is running and that GPG_AGENT_INFO has been set up properly. In case you're using the console/curses pinentry, it will be executed on the same tty as pwmd. This issue may potentially be fixed in newer versions of gpg that could include an option to specify the tty when running gpg-agent and the pinentry program. The X11 pinentry, however, doesn't encounter this problem.
Currently, there is no specific interface for the daemon. However, you can employ the socat utility, which establishes two bidirectional byte streams and transfers data between them. These streams may include, for example, a file, a pipe, a device (terminal or modem), a socket (UNIX, TCP, or UDP), etc. As such, you can utilize this utility like so: socat GOPEN:$HOME/.pwmd/socket.
Finally, a library is being developed to make it easier for applications, such as smtp, pop, imap, www, and others, to use the daemon.
