It will ask you to configure “VALIDATE PASSWORD PLUGIN” which is used to test the strength of the MySQL users passwords and improve the security.
There are three levels of password validation policy, low, medium, and strong. Enter 0 , 1 or 2 as per your requirements.

Next, it will ask you to set a password for the MySQL root user.
