\modulesynopsis{Portable reading of passwords and retrieval of the userid.}
The \module{getpass} module provides two functions:
\begin{funcdesc}{getpass}{\optional{prompt}}
Prompt the user for a password without echoing. The user is
prompted using the string \var{prompt}, which defaults to
\code{'Password: '}.
\end{funcdesc}
\begin{funcdesc}{getuser}{}
Return the ``login name'' of the user.
This function checks the environment variables \envvar{LOGNAME},
\envvar{USER}, \envvar{LNAME} and \envvar{USERNAME}, in order, and
returns the value of the first one which is set to a non-empty
string. If none are set, the login name from the password database
is returned on systems which support the \module{pwd} module,
otherwise, an exception is raised.
\end{funcdesc}
