Generate random password in Dynamic AX

Just like OTP (one time password) for email this below code generates for alphabet.

static void Generate_Password_Random()
 {
     int i;
     RandomGenerate random = new RandomGenerate();
     str password;
     int passwordLength = 8;
     ;

     for (i=1; i<= max(2, passwordLength); i++)
     {
         if (i mod 2)
             password += num2char(random.randomInt(char2num(‘a’, 1), char2num(‘z’, 1)));
         else
             password += num2char(random.randomInt(char2num(‘0’, 1), char2num(‘9’, 1)));
     }

     info(password);
 }
