Normally, you can add, edit and delete users and passwords from the back-end User Manager. To do this, you must be logged in as a member of the Super Administrator group.
In some situations, this may not be possible. For example, your site may have been "hacked" and had the passwords or users changed. Or perhaps the person who knew the passwords is no longer available. Or maybe you have forgotten the password that was used.
In these cases, it is still possible to fix up the Joomla! database so you can log back in as a Super Administrator. There are three possible methods discussed below.
If you have access to the email address that was used for the admin user, and you have made the "lost password" feature available on the front end, the simplest thing is to do is to use the "lost password" Front-end function. The site will send an e-mail to the user's e-mail address and allow you to change the password.
If this method will not work, you have two other options, both of which require working with the MySQL database directly.
If the admin user is still defined, the simplest option is to change the password in the database to a known value. This requires that you have access to the MySQL database using phpMyAdmin.
If changing the password won't work, or you aren't sure which user is a member of the Super Administrator group, you can use this method to create a new user.
INSERT INTO `jos_users` (`id`, `name`, `username`, `email`, `password`, `usertype`, `block`, `sendEmail`, `gid`, `registerDate`, `lastvisitDate`) VALUES (NULL, 'Administrator2', 'admin2', 'email@example.com', 'd2064d358136996bd22421584a7cb33e:trd7TvKHx6dMeoMmBVxYmg0vuXEA4199', 'Super Administrator', 0, 1, 25, '0000-00-00 00:00:00', '0000-00-00 00:00:00'); INSERT INTO `jos_core_acl_aro` VALUES (NULL, 'users', LAST_INSERT_ID(), 0, 'Administrator', 0); INSERT INTO `jos_core_acl_groups_aro_map` VALUES (25, '', LAST_INSERT_ID());
The examples above change the password to "secret". Two other possible values are shown below:
- password = "this is the MD5 and salted hashed password" ------------------------------------------------------ - admin = 433903e0a9d6a712e00251e44d29bf87:UJ0b9J5fufL3FKfCc0TLsYJBh2PFULvT - secret = d2064d358136996bd22421584a7cb33e:trd7TvKHx6dMeoMmBVxYmg0vuXEA4199 - OU812 = 5e3128b27a2c1f8eb53689f511c4ca9e:J584KAEv9d8VKwRGhb8ve7GdKoG7isMm
