64 | The <tt class="module">getpass</tt> module provides two functions: | |

71 | Prompt the user for a password without echoing. The user is | |
72 | prompted using the string <var>prompt</var>, which defaults to | |
73 | <code>'Password: '</code>. | |
74 | Availability: Macintosh, <span class="Unix">Unix</span>, Windows. | |

88 | returns the value of the first one which is set to a non-empty | |
89 | string. If none are set, the login name from the password database | |
90 | is returned on systems which support the <tt class="module"><a href="module-pwd.html">pwd</a></tt> module, | |
91 | otherwise, an exception is raised. | |
