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.

To configure Email OTP verification,

  1. In your form builder, navigate to Settings.

  2. Click OTP Verification from the left menu and click Configure Now.

    OTP Verification - Click Configure Now

  3. In the pop-up, select Email.

    Select Email

  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.
  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

Click Save.
You can check the OTP method, Email, and  the number of times OTPs have been re-sent for each submitted entry (Retry Count) in the  All Entries section of your form under the OTP Verification Details column.

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.

  • OTP verification cannot be configured if Save & Resume option is enabled in your Form Settings.
