The show-passphrase option is coming to pinentry soon (tm):

  https://bugs.gnupg.org/gnupg/issue2139

We also have support for saving the passphrase in an external password
manager.  This should only be an option if "OPTION
allow-external-password-cache" was set.  The appropriate string is
saved in pinentry->default_pwmngr (which is set via "OPTION
default-pwmngr").

Thanks!
