Solution 1

I always use the RegExLib website, they have a lot of regular expressions. A search query for password[^] will do.

You can choose between many different kinds.

Solution 2

I think this Regular Expression would solve your problem,

<br />
^(?=.{8,})(?=.*[0-9])(?=.*[a-z])(?=.*[A-Z])(?=.*[@#$%^&+=]).*$

Try with this regular expression and let me know the result.

You have to learn about Regular expressions. Check these, you could build yourself new expressions.
