Master User

April 19th, 2013

This plugin for the Joomla CMS allows selected administrators to log into registered user accounts using their own administrator passwords.

Optionally this facility can be restricted to selected administrators only, or all administrators can be allowed to do this.

Since administrators use their own passwords these are encrypted and stored securely in the database as normal, so this should not compromise the security of your site. Additionally you can restrict the facility to selected IP addresses only. The plugin does not allow you to log in as another administrator.

This plugin works with the standard Joomla login and extensions that use this, and will also work with Community Builder if the Login Field Type is set to ‘Username, email or enabled CMS authentication plugins’.

Our tests show that it works with other extensions such as the Virtuemart customer accounts as well – it should work with any extensions that support Joomla authentication plugins and the core Joomla user account.


Upload and install using the Joomla installer. Enable it in the plugin manager. Either set the ‘enable all administrators’ parameters to yes, or list the ids of selected administrators as a comma separated list in the ‘Master User Ids’ input box. If you wish to restrict by IP address then list allowed IP addresses as a comma separated list.

Now, if you are an administrator you can log into your site as another user by supplying the username plus your own administrator password. As far as the site is concerned you will be that user.
