How change recover forget Joomla administrator password?

If you use Joomla, if you forget your admin username or password, you can change it easily with a simple MySQL query. The most convenient way to manage the database is through the phpMyAdmin tool. Go to your cPanel and click on phpMyAdmin in the Databases box. (If you are not using cPanel or do not have phpMyAdmin, you can run the query directly for Joomla's database.)

Once in the phpMyAdmin select the Joomla's database from the drop-down menu at left. The page will refresh and the database's tables will be displayed on it. Open the SQL tab (look at the top navigation bar).

In the text field write the following SQL query:

UPDATE `jos_users` SET `password` = MD5( 'your_password' ) WHERE `jos_users`.`username` = "admin" ;

"your_password" - replace this with the new password you wish to use.
"admin" - replace this if your admin username is different.

Once you are ready, click on the GO button to submit the query. If everything goes fine without errors, you should be able to login to Joomla with the new password.

Note: These instructions are valid both for Joomla 1.5 and Joomla 1.0.*.

You can also Set the password to a known MD5 value

- password = "this is the MD5 hashed password"
------------------------------------------------------
- admin = 21232f297a57a5a743894a0e4a801fc3
- secret = 5ebe2294ecd0e0f08eab7690d2a6ee69
- OU812 = 7441de5382cf4fecbaa9a8c538e76783
Paste the hashed password into the field, save the change, and log-in using the new password.
Immediately change your password to something more secure!
