If you forgot root password for your MySQL database server running under Microsoft Windows, there is still a way to access your database and even reset your password using the command prompt.
Follow next steps:
1. Stop your MySQL server completely. This can be done from Wamp(if you use it), or start “services.msc” using Run window, and stop the service there.
2. Open your MS-DOS command prompt using “cmd” inside the Run window. Then go to your MySQL bin folder, such as C:\MySQL\bin. Path is different if you use Wamp.
3. Execute the following command in the command prompt:
mysqld.exe -u root --skip-grant-tables
4. Leave the current MS-DOS command prompt as it is, and open a new MS-DOS command prompt window.
5. Go to your MySQL bin folder again.
6. Enter “mysql” and press enter.
7. You should now have the MySQL command prompt working. Type “use mysql;” so that we switch to the “mysql” database.
8. Execute the following command to update the password:
UPDATE user SET Password = PASSWORD('your_new_passowrd') WHERE User = 'root';
However, you can now run almost any SQL command that you wish.
After you are finished close the first command prompt, and type “exit;” in the second command prompt.
You can now start the MySQL service. That’s it.
