sudo mysql_secure_installation

You will be asked to configure the VALIDATE PASSWORD PLUGIN which is used to test the strength of the MySQL user’s passwords and improve the security. Type Y to start the Validate Password plugin and you will get the following prompt:

Enter the number for the password strength and press the Enter key:

On the next screen, enter and re-enter the password:

The system will then display the strength of the password you provided and also ask you if you want to continue with the password.

mysql -u root -p

To check which authentication method each MySQL user uses, run the following command:

mysql> SELECT user,authentication_string,plugin,host FROM mysql.user;

Change the authentication method from auth_socket to mysql_native_password . You can do that by running the following command:

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'YOUR_STRONG_PASSWORD';

After executing the ALTER USER command, run the following command:


Now, if you recheck the authentication method for your MySQL user accounts using the following command, you see that your root user is now using the mysql_native_password plugin for authentication:

mysql> SELECT user,authentication_string,plugin,host FROM mysql.user;
