HTML Form Pattern Regex

Question

I'm trying to have a Reg Exp for the following:

8 characters min
1 uppercase (at least)
1 lowercase (at least)
1 digit (at least)
Excluding: + @ &

I have the following but I can't seem to have the right combo of group/sub-group to make them work together:

[^+@&](?=.*\d)(?=.*[a-z])(?=.*[A-Z])).{8,}

I need guidance!

You need to use anchors and place the negated class after your assertions.

^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)[^+@&]{8,}$
