Set up DOI via OTP

As well as using DOI via email confirmation, you can also use DOI via one-time password (OTP) codes.

  1. Go to Publish and click on Double opt-in (GDPR).
    go to DOI
  2. Enable Double opt-in via OTP code or click on EDIT if you already enabled it.
    enable DOI via OTP
  3. Select the email field for Email recipient if not already there automatically, make any other changes to the setup, and click on SAVE & CLOSE.

  4. Your audience will then receive an email 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 email 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 email verification.
