Save a joomla website on my pc without Id & pass

A client is asking to improve his website but can't give me the admin id & pass (for security reasons).

Is there a way to put his joomla website in my hard di开发者_如何学JAVAsk in order to work on it ????

The easiest way to do this would be for the client to set up a new super administrator account, then make a backup copy of the website using Akeeba Backup. You can then install that copy on your PC or server to do the necessary work. When you are done, simply make a new backup and have them restore from your backup to update the live site.

When they update they can remove the additional super admin account they set up for you.
