If you forget your root MariaDB password, don’t worry and be sad because it can be reset easily with this tutorial.

1. Stop the current MariaDB server instance, then restart it with an option to not ask for a password:

   systemctl stop mariadb
   mysqld_safe --skip-grant-tables &
   

2. Reconnect to the MariaDB server with the MariaDB root account:

   mysql -u root
   

3. Use the following commands to reset root’s password. Replace password with a strong password:

   use mysql;
   update user SET PASSWORD=PASSWORD("password") WHERE USER='root';
   flush privileges;
   exit
   

4. Then restart MariaDB:

   systemctl start mariadb
   

Done, everything will be fine. Now you should be able to access again with new password we update before.
