Solving MySQL Root User Password Issues on MacOS

Many users encounter challenges when setting the MySQL root user password on MacOS. This article explores the issue and provides comprehensive solutions to rectify it.

When attempting to set the root user password using mysqladmin, users may find that they can still access the MySQL command line without the password. This is a common occurrence that can be resolved.

Solution:

1. Flush Privileges:
   Log into the MySQL terminal and execute the FLUSH PRIVILEGES command.

2. Alternative Method:
   If FLUSH PRIVILEGES doesn't resolve the issue, execute the following commands in the MySQL terminal:

   • mysql -u root
   • USE mysql;
   • UPDATE user SET password=PASSWORD("NEWPASSWORD") WHERE User='root';
   • FLUSH PRIVILEGES;
   • quit
     Replace NEWPASSWORD with the desired password.

Additional Notes:

• For MySQL 5.7 and above, the password field is renamed to authentication_string. Use the following query to change the password:

  • UPDATE user SET authentication_string=PASSWORD("NEWPASSWORD") WHERE User='root';

• For MySQL 8.0 and later, use the following query:

  • ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';

By following these instructions, users can effectively set the MySQL root user password on MacOS and ensure secure access to their database.
