How Do I Recover a Lost MySQL Username and Password?

Recovering MySQL Username and Password

Losing your MySQL username and password can be a daunting experience, but it's not an insurmountable one. Here's a step-by-step guide to retrieve them:

Steps:

  1. Stop the MySQL Process:

    • Use the service command or kill the process using kill -9 command.
  2. Start MySQL with Skip-Grant-Tables Option:

    • Add the --skip-grant-tables flag when starting MySQL. This will temporarily disable the user verification.
  3. Start MySQL Console as Root:

    • Execute mysql -u root -p to open the MySQL console as the root user.
  4. List MySQL Users:

    • Run the SELECT * FROM mysql.user; query to display all users.
  5. Reset Password:

    • Use the UPDATE mysql.user SET Password=PASSWORD('[password]') WHERE User='[username]'; query to reset the password for the desired user.
  6. Exit MySQL Console:

    • Type exit to exit the MySQL console.
  7. Restart MySQL Normally:

    • Remove the --skip-grant-tables option when starting MySQL to re-enable user verification.
  8. Test the New Password:

    • Use the mysql -u [username] -p command to log in using your recovered username and password.

Caution:

  • Remember to disable the --skip-grant-tables option after resetting the password to maintain the security of your database.
