OTP Verification - Email | Zoho Forms - User Guide

Setting up OTP Verification via Email

When you configure Email OTP verification, respondents who access your form via public links will be required to enter their email address to receive a One-Time Password and verify it before they can access the form.

Email OTP

To configure Email OTP verification,

  1. In your form builder, navigate to Settings > Spam Control.

  2. Click OTP Verification and click Configure Now.

    Click Configure Niow

  3. In the pop-up, select Email.

    OTP delivery method

  4. Select the From address. If you wish to display a From Name while sending emails, click Add From Name.
    Note : If you select notifications@zohoforms.com to be the From address, then the form admin's email address will be set as From Name by default and this cannot be modified.

  5. You can change the default email Subject and the OTP message to be sent in the email as required. You can also include the link to the OTP Verification page where the respondent is required to enter the received OTP in the email message by clicking the   icon. If the respondent has entered the OTP, then the link in the email will redirect to the form and not to the OTP Verification page.
  6. OTP expiration time:  Set the time within which a respondent is required to enter the OTP verification code.
  7. Number of OTP resend requests allowed:  You can set the number of times a respondent can opt to resend the OTP code to their email.
  8. Map OTP-verified Email to a form field:  You can pre-fill an email field in the form with the verified email address by selecting the required form field from the dropdown.

    Note :

    • The following properties configured for the selected Email field  will be applied to the email address entered by the respondent for verification:

      • Domain Validation

      • Character Limit

      • No Duplicates Validation

      • Email input confirmation 

    • If you want to restrict your respondent from editing the pre-filled Email field in the live form, select the Disable Field option under Email field Properties.   

  9. To add an extra layer of security and prevent spam entries, you can include a Zoho Forms CAPTCHA under Spam Control and evaluate if it is a human or a bot that is filling your form. Learn more  
  10. Click Save.

Check out the FAQ on how to access an OTP Verification enabled form with the same email address when the field is mapped to a form field with the No Duplicate  property.
Note : Only records from the last 30 days will be listed under OTP Audit: Non-submitted Records.

You can change the default live form OTP messages under Settings tab > Custom Messages.
If you choose to translate your form into different languages, the OTP verification messages displayed on accessing the form link will also be translated into the respective languages.

Note The option to configure OTP Verification is available only in our paid plans.
