Regex 2 Numbers OR Special Characters

Question

So i'm trying to create a Regex which does the following:

Min 12 Characters, Requires Uppercase, Requires Lowercase, Requires 2 Numeric values OR 2 Special Characters.

At the moment i have the following:

~^(?=\P{Ll}*\p{Ll})(?=\P{Lu}*\p{Lu})(?=.*[!@#$%^&*()]|\D*\d).{12,}~u

Which does 1 numeric OR 1 special character, not 2. I've tried adding {2} to the OR condition, however, this requires a combination of two which is incorrect.

Any help would be appreciated.

Answer 1

You should replace (?=.*[!@#$%^&*()]|\\D*\\d) lookahead with (?:(?=(?:[^!@#$%^&*()]*[!@#$%^&*()]){2})|(?=(?:\\D*\\d){2})) . The regex will look like

'~^(?=\P{Ll}*\p{Ll})(?=\P{Lu}*\p{Lu})(?:(?=(?:[^!@#$%^&*()]*[!@#$%^&*()]){2})|(?=(?:\D*\d){2})).{12,}$~u'

See the regex demo .

The lookahead matches a location that is immediately followed with

• (?:[^!@#$%^&*()]*[!@#$%^&*()]){2} - two repetitions of any 0+ chars other than !@#$%^&*() chars followed with a char from the !@#$%^&*() list
• | - or
• (?=(?:\\D*\\d){2} - two repetitions of any 0+ non-digit chars followed with a digit
