This template creates a padlock icon in the upper-right corner of a page to indicate that it is protected. The icons are designed to provide a clear visual identification of the level of protection that has been invoked or the action that has been protected from being performed.
This template does not in itself protect a page, and only administrators can change the protection level of a page.
When to use
To provide transparency to all users, this template should be applied on all pages which have been protected by an administrator. Pages that are automatically protected by the MediaWiki software, pages that have been creation protected, and highly-visible pages that are permanently protected do not require a visual indicator.
The style of the padlock indicator is dependent on the switch used. The template can also display a second padlock for use in situations in which two modes of protection are applied to a page.
