Sometimes it happens that you forget your password that prevents you from logging in. There are certain solutions if you happen to confront such situations. The first and easy step is to click on forgot password link. If you have access to the email submitted already for the administrator, the website will send an email to you and this will allow you to reset the password. But forgot password link will not send email for resetting super administrator password. But Joomla can send forgot username for a super administrator to your email.
Another way is to get connected with the webhosting and MySQL database to change the password to a known value. Login to webhosting providers c panel and go to phpMyAdmin and select the databases on the server. Usually the drop down menu shows single database that are present in the server. If you have used jos- as the prefix, which is the default, the table will be seen as jos_users. Select the database for your Joomla site and click browse. Now jos_users table will let you see the usernames in the middle column. Select the username for which you want to change the username and password. Press edit icon and in the row Password select MD5 in the dropdown and paste the exact d2064d358136996bd22421584a7cb33e:trd7TvKHx6dMeoMmBVxYmg0vuXEA4199 and click Go. phpMyAdmin now will show you the result Affected rows:1. Now login to your site with administrator and the changed password is secret. Now you can change the password to a secure value. If you think your site has been asked, you should change the passwords for other users on the site as well.
Another method is to temporarily remove the PHP authentication. Go to plugins/authentication/joomla/joomla.php and modify the line 1.if ( $crypt == $testcrypt) { to 1.if ( true /* $crypt == $testcrypt */ ) { . Now you can login back with any password. Now reset your password and undo the modification in the above line. Now onwards please make sure that you dont forget the super administrator password.
