How to change the Joomla 2.5 admin password?
The Joomla 2.5 administrator's password can be altered from the Joomla 2.5 admin area -> Users -> User Manager. Select the check box next to the administrator user name and click on the Edit button located at the top-right Joomla menu.
In the Edit Profile section you should enter and confirm the new password. Save the change.
Next time when you want to open the Joomla's administrator area use the new admin password.
Alternatively, you can change the password of your admin user via cPanel -> Joomla! Toolkit in case you don't have access to your Joomla admin area.
