When you share a form publicly, Zoho Forms provides you with various options to ensure that you receive form entries from valid users. One such option is OTP Verification where you can choose to send a verification code (OTP) to your respondents' email/mobile before providing access to your form to avoid receiving any invalid form entries.
How OTP Verification Works?
Respondent clicks the public URL of your form.
OTP Verification page opens.
Respondent enters an email address/mobile number to receive the OTP.
Respondent receives an email/SMS with the OTP.
Respondent enters the OTP on the verification page.
Once the OTP is verified, form opens for the respondent to access.
