Subject: [PATCH] Allow secure user password update.

This patch allows the ability for user password to be updated via
a command prompt so the password doesnt show up in the bash history.
The prompted password is asked twice to verify the match.
If user cntl-D's the prompt a message appears suggesting user to use
either of the options to update the password.

Fixes: bug#938315
