You can also use DOI via one-time password (OTP) codes that are sent via SMS.

  1. Go to Publish and click on Double opt-in (GDPR).
    go to DOI
  2. Enable Double opt-in via OTP (SMS) or click on EDIT if already enabled.
    enable DOI via OTP SMS
  3. Choose whether to save DOI-unconfirmed leads, select the phone number field for SMS recipient if not already there automatically, select your SMS vendor, enter the API key, and click on SAVE & CLOSE.

  4. Your audience will then receive an SMS containing an OTP code which they have to enter into the Riddle they are taking part in.

Please note:

You cannot have the OTP verification and DOI SMS active at the same time.

If you have your Riddle connected to a leaderboard and turn on the OTP verification, users will be sent one code that combines the functionality for entering a leaderboard and verification.
