6.12 getpass -- Portable password input

The getpass module provides two functions:

Prompt the user for a password without echoing. The user is prompted using the string prompt, which defaults to 'Password: '. Availability: Macintosh, Unix, Windows.

Return the ``login name'' of the user. Availability: Unix, Windows.

This function checks the environment variables LOGNAME, USER, LNAME and 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 pwd module, otherwise, an exception is raised.
