MySQL Your Password does not Satisfy the Current Policy Requirements on linux machine

After installation of Mysql on one of our Linux machine I am unable to grant permission for user and getting the following error

Your Password does not Satisfy the Current Policy Requirements

You can check the current password policy by connecting MySQL and run the following command .

SHOW VARIABLES LIKE 'validate_password%'

The simple method to solve this set the password policy to "LOW" and I am not recommended this method. always keep the secure and complex passwords.

SET GLOBAL validate_password_policy=LOW;
