I'm trying to write regex to validate the password for the given rule.

Passwords must be at least 8 characters in length and contain at least 3 of the following 4 types of characters:

• lower case letters (i.e. a-z)
• upper case letters (i.e. A-Z)
• numbers (i.e. 0-9)
• special characters (e.g. !@#$&*)

I was going through this discussion and found this really great answer over there.

Now I'm trying to write regex for the mentioned requirements and I came up with the solution like this

^(?=.*[A-Z])(?=.*[!@#$&*])(?=.*[0-9])(?=.*[a-z]).{8,}|
(?=.*[!@#$&*])(?=.*[0-9])(?=.*[a-z]).{8,}|
(?=.*[A-Z])(?=.*[0-9])(?=.*[a-z]).{8,}|
(?=.*[A-Z])(?=.*[!@#$&*])(?=.*[a-z]).{8,}|
(?=.*[A-Z])(?=.*[!@#$&*])(?=.*[0-9]).{8,}$

and it is working perfect see rubular but I want to optimize these regex and I'm not sure If there are any way to simplify this. Any suggestion will be appreciated.
