SteamAuth is a MediaWiki extension that allows users to sign in with Steam. This plugin uses PluggableAuth.

The extension is designed to be used as the only form of authentication for your wiki.

Special thanks to LightOpenID.


Note Note: This extension requires PluggableAuth to be installed first.

  • Download and place the file(s) in a directory called SteamAuth in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php :
    wfLoadExtension( 'SteamAuth' );
  • Configure as required.
  • Yes Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Recommended Settings[edit]

Disabling normal account creation is strongly recommended. You can do so by adding the following lines to the bottom of your LocalSettings.php:

$wgGroupPermissions['*']['createaccount'] = false;
$wgGroupPermissions['*']['autocreateaccount'] = true;

It is also recommended to use a plugin such as Realnames to display the user's display name rather than their ID.


Flag Default Description
$wgSteamAuth_Key "key" Your steam developer API key (Available from https://steamcommunity.com/dev/apikey)
$wgSteamAuth_AppID null (Optional) If set, only users that have this app/game in their Steam library can login and create accounts.
