Database Password is required in Xampp in windos

on xampp Database Password * is required, where my database password is none in Xampp.
what should i do?

ehsan, this is a good question. XAMPP has no default MySQL password, as it is intended for local development and testing, rather than production use. This makes it easier to get up and running. However, from a security view I disagree with this policy for a number of reasons. I suggest you set your MySQL password to something secure, following these instructions. Good luck!
