    public static boolean passCheck(String pass){
        if (pass.length() < 10){
            return false;
        }
        int digitsCount = 0;
        for(int i = 0; i < pass.length(); i++){  
            char c = pass.charAt(i);
            if (c >= 'a' && c <= 'z'){
                //is letter
            } else if (c >= 'A' && c <= 'Z'){
                //is letter
            } else if (c >= '0' && c <= '9'){
                digitsCount++;
            } else {
                return false;
            }
        }
        if (digitsCount < 2){
            return false;
        }
        return true;
