# `pwd` --- The password database

This module provides access to the Unix user account and password database. It is available on all Unix versions.

Disponibilité: Unix, not WASI, not iOS.

Password database entries are reported as a tuple-like object, whose attributes correspond to the members of the `passwd` structure (Attribute field below, see `<pwd.h>`):

Index | Attribut | Signification
--- | --- | ---
0 | `pw_name` | Nom d’utilisateur
1 | `pw_passwd` | Optional encrypted password
2 | `pw_uid` | Numerical user ID
3 | `pw_gid` | Numerical group ID
4 | `pw_gecos` | User name or comment field
5 | `pw_dir` | Répertoire d’accueil de l’utilisateur
6 | `pw_shell` | User command interpreter

The uid and gid items are integers, all others are strings. `KeyError` is raised if the entry asked for cannot be found.

Note

In traditional Unix the field `pw_passwd` usually contains a password encrypted with a DES derived algorithm. However most modern unices use a so-called shadow password system. On those unices the pw_passwd field only contains an asterisk (`'*'`) or the letter `'x'` where the encrypted password is stored in a file `/etc/shadow` which is not world readable. Whether the pw_passwd field contains anything useful is system-dependent.

It defines the following items:

pwd.getpwuid(uid)

  Return the password database entry for the given numeric user ID.

pwd.getpwnam(name)

  Return the password database entry for the given user name.

pwd.getpwall()

  Return a list of all available password database entries, in arbitrary order.
