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.
  • Add the following code at the bottom of your LocalSettings.php :
    wfLoadExtension( 'MinimumNameLength' );
  • Configure as required
  • Yes Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.


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.
