^ // start of input
(?=.*?[A-Z]) // Lookahead to make sure there is at least one upper case letter
(?=.*?[a-z]) // Lookahead to make sure there is at least one lower case letter
(?=.*?[0-9]) // Lookahead to make sure there is at least one number
[A-Za-z0-9]{6,} // Make sure there are at least 6 characters of [A-Za-z0-9]
