How to Recover Your Lost MySQL Username and Password?

Retrieving MySQL Username and Password When Lost

Losing your MySQL username and password can be frustrating, but it's not uncommon. Here's a step-by-step guide to help you retrieve this vital information:

Step 1: Stop MySQL Process

  • Shutdown your MySQL server to prevent any changes while you retrieve your credentials.

Step 2: Start MySQL with Grant Bypass

  • Restart MySQL with the --skip-grant-tables option. This disables password checks, allowing you to proceed without a password.

Step 3: Connect as Root

  • Connect to the MySQL console as the root user using the -u root option. Since password checks are bypassed, you won't be prompted for a password.

Step 4: List MySQL Users

  • Run the following query to list all MySQL users:

    SELECT * FROM mysql.user;
    Copy after login
  • This will display a list of users, their usernames, and encrypted passwords.

Step 5: Reset Password

  • Identify the user account you need to regain access to.
  • Update the password using the following query:

    UPDATE mysql.user SET Password=PASSWORD('[password]') WHERE User='[username]';
    Copy after login
  • Replace [password] with your desired new password and [username] with your actual username.

Step 6: Secure the Server

  • After resetting the password, it's crucial to revert the server settings by:
  • Stopping the MySQL process.
  • Starting MySQL normally (without the --skip-grant-tables option).

Caution:

  • Failing to restore the default MySQL security settings after retrieving your credentials could expose your database to unauthorized access.
