Master User

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.
Usage
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.
********* News *****
The latest release, 2.0.0 now includes support for Joomla 3.0
********************
We use it on our cloned websites (rather than live websites) to prevent privacy issues and to protect the actual timing of user's login.
My one recommendation would be to add the ability to use the user's email address in addition to their username as the 'username'.
Since we're using emailasusername plugin, we just use email address for normal login process.
It is working perfectly with Joomla 2.5.3. However, it does not work with Community Builder's login module which is perfectly fine. There are creative ways to have more than one login module. Joomla is fantastic about that. You can also hide the original Joomla Module or turn it off (if using CB) when it is not needed.
Thank you for making such a great plugin. It really helps an admin see ACL in action real time.
Very glad to hear that you like the plugin. However please note that it does work with the Community Builder login, in CB you need to set the 'Login Field Type' option (on the congiuration->general tab) to 'Username, email or enabled CMS authentication plugins'. This enables CB to process Joomla authentication plugins as well as uing its own system of authentication.
Ingenious idea, well thought through in terms of available parameters. I had it downloaded, installed, configured and successfully tested in about two minutes. Many thanks for this plugin.
Install is 2 files which I reviewed in detail, all looks safe and and secure to me. Can't go wrong following the directions above (on joomla extensions page). FYI - You will find the settings under Extensions / Plugin Manager as 'Authentication - Master User'.
Masterpassword used to be my plug in of choice in this category, until it failed for some reason.
Once I'd actual set the plugin up to allow my super admin account access to the plug-in it all worked like a dream. Our site uses JFusion as well to log into a VB forum, and this plug-in worked in conjunction with that which is exactly what we needed!
It was a slight pain to have to go through the virtual mart check out process to download
I can will be keeping the plugin installed as it will also help admins fix user account issues when the site goes live.
Well done.
