Losing/Forgetting your ISPConfig 3 administrator password is annoying, but can happen to anyone! (link tip: KeePassX) To reset the password, you need to follow the few steps below.
You will need the root login for MySQL, you can find that information a ISPConfig 3 config file.
$clientdb_host = ‘localhost’;
$clientdb_user = ‘root’;
$clientdb_password = ‘VerySecurePassword’;
You can now log into you MySQL server with the information extracted from mysql_clientdb.conf:
mysql -h localhost -p dbispconfig
UPDATE sys_user SET passwort = md5('YourNewPassword') WHERE username = 'admin'; FLUSH PRIVILEGES; quit;
You can now log into your ISPConfig 3 web interface with your new admin password.
