Regex for Password must contain 8 characters, 2 letter both lower or uppercase letters and one special character ' * ' 5 digit number

Question

I want to create an expression for password as below:

Regex for passwords that must contain 8 characters, start with 2 lower or uppercase letters, contain one special character * and a 5-digit number.

E.g.: az*12345

It must be start with 2 characters;
Contain only single *;
End with 5 digits.

I have tried it with this pattern: (?=(.*[^a-zA-Z]){2})(?=.*[*]{1})(?=(.*\d){5}).{8}$

However, it yields almost the same results as a regex above. It starts with any character but I want the exact above mentioned pattern. I know I am close to it. Please suggest me what I should do.

Must the special character be the asterisk (*)? Wouldn't ^[a-zA-Z]{2}\*\d{5}$ be sufficient then? — Paul
If you don't want it to start with any character, don't make it start with .*. That means any character zero or more times. — Nick

If you wish to match just [2-letters]+[*]+[5-digits] pattern, here is what you are looking for:

^[a-zA-Z]{2}\*[0-9]{5}$.
