Sending OTP

We need to fully verify your account here in my end, what I'm going to do is I will be sending you a one-time passcode and may, I know what method that you preferred to receive the one-time passcode would it be fine if I send it to your mobile number?

OTP EXPIRE:

Please be reminded that the code will be expire after 10 minutes, once you receive the one-time pass code you can provide to me, while waiting for the code may I know how's your day so far?
