Regex for at least one uppercase letter, one lowercase, one number OR special character

Question

The password validation requirements for my input field are as follows: "Password should contain at least one uppercase, one lowercase letter, one number OR special character".

This is the regex for 1 uppercase, 1 lowercase, 1 number AND one special character

^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[$@$!%*?&])[A-Za-z\d$@$!%*?&]

Are you asking us to explain your own password requirements, or the regex? — Ken White

I think you need a regex like this:

^(?=.*[a-z])(?=.*[A-Z])(?=.*[\d$@$!%*?&]).*$

In [\d$@$!%*?&] you have at least one number OR one special character.
