Question

I have found regex patterns that can enforce one special sign and one digit and a minimum of characters.

But does anyone have a more realistic example of a regex for enforcing f.ex.

2 or more digits
2 or more alphabetic
2 or more non-alphabetic non-digit

Minimum length 8

Answer 1

You could use something like so:

• 2 or more digits: \d{2,}
• 2 or more alphabetic: [A-Za-z]{2,}
• 2 or more non-alphabetic: [^A-Za-z0-9]{2,}.

I would recommend you have seperate regular expression for different checks. This will help making a more maintainable solution. For length purposes I would recommend using the length property which most languages provide.
