Is it possible to change cookies?

Question

PHP

I downloaded the login and registration script in short))
There, only the username is saved in cookies. It's safe?
Such a question: can the user in the cookie stupidly change the username to something else? After all, then the site will take him for another person

Answer 1

I think native PHP sessions will be enough for you.
