The One Time Passcode (OTP) can be found in the same email address you used to sign up for the VIP Program, which should also be the email address that is currently linked your Design Home account.

The One Time Passcode will expire in 24 hours. You will have to request a new passcode if you don't use it beyond the 24 hours.

If you requested multiple OTPs, only the most recent one can be used to verify the email address.
