The Minimum Name Length extension allows to set a minimum length for user names which will be enforced during account creation.


  • Download and place the file(s) in a directory called MinimumNameLength in your extensions/ folder.

To users running MediaWiki 1.27 or earlier:

The instructions above describe the new way of installing this extension using wfLoadExtension() If you need to install this extension on these earlier versions (MediaWiki 1.27 and earlier), instead of wfLoadExtension( 'MinimumNameLength' );, you need to use:

require_once "$IP/extensions/MinimumNameLength/MinimumNameLength.php";


To configure the minimum name length for a username, set $wgMinimumUsernameLength in the "LocalSettings.php" file, after the call to include the extension as described in the installation section, e.g.

$wgMinimumUsernameLength = 8;
10 is the default setting. In case you are fine with this you do not need to do anything.
