When you are hosting an exclusive event, running a giveaway, or collecting critical business data, every interaction needs to feel authentic, secure, and seamless for the user. This is where OTP (one-time password) verification is useful for safeguarding form access.
What is OTP verification, and why does it matter?
OTP verification is a process where users receive a unique, time-sensitive code to confirm their identity. This ensures:
- Data submitted through the form is authentic
- Unauthorized access is prevented
- Businesses comply with security standards, especially for sensitive transactions
Imagine hosting a holiday giveaway where participants must confirm their entry via OTP. This eliminates spam entries and ensures genuine participation—win-win!
OTP verification in Zoho Forms
Multi-channel verification options
Zoho Forms offers the flexibility to choose from several options for OTP delivery.
Email remains a trusted and professional channel for communication, making it ideal for businesses and formal transactions. By sending OTPs via email, Zoho Forms provides a reliable method to validate user identities while integrating seamlessly into workflows that rely on official correspondence. For example, you can ensure authenticity in job applications by verifying candidates via their professional email addresses.
SMS
With SMS being one of the most immediate and accessible forms of communication, it’s no surprise that it’s a go-to choice for OTP verification. SMS ensures that users can quickly receive and input their OTP from anywhere, making it ideal for situations where speed and convenience are key. For example, you can use SMS OTP verification to keep online purchases secure and prevent fraudulent orders. Deliver OTPs instantly, even without internet access. SMS has a high readability with over 90% of SMS messages opened within minutes and has universal compatibility across all mobile devices.
For users who prefer a conversational, modern touch, WhatsApp OTP verification works well. As one of the most widely used messaging apps globally, WhatsApp provides a familiar and engaging platform for receiving OTPs. For example, confirm participation for exclusive events or workshops with a casual yet secure approach.
OTP expiration settings
Use the OTP expiry settings in Zoho Forms to strike the perfect balance between security and user convenience. Configure a time limit (for example, 2 minutes) for the OTP to ensure that users must act promptly and minimize the risk of misuse or interception.
Why is it essential?
Expiring OTPs add an extra layer of protection, especially for time-sensitive forms like bookings or reservations.
Synchronize OTP and session expiry: A perfect match
With the option to set the same expiration time for OTP sessions, administrators can synchronize OTP validity with the session duration. When enabled, both the OTP and the session expire simultaneously, providing an added layer of security. This is useful when OTP security needs to mirror session duration, like in high-stakes financial forms.
For example, a banking form allows users three minutes to input OTP to access the form, syncing OTP expiration with the session.
Manage OTP resend requests
Excessive OTP requests can strain systems and reduce user satisfaction. Zoho Forms lets you limit how many times users can request a new OTP. You can even set a cooldown period (e.g., 30 seconds) before users can request a resend.
Expiring OTP-validated form links
Security doesn’t end with OTP verification. Zoho Forms allows you to set an expiration period for the OTP-validated form link itself. Define how long (e.g., 2 hours) the form remains accessible post-verification.
Custom messages for expired links
No one likes hitting a dead end! With Zoho Forms, you can create a custom link expiration message to guide users when their OTP-validated link expires. This enhances user experience by providing clarity and directing users to the next step.
For example, “Your session has expired. Please request a new OTP to continue.” ensures users stay informed and take action.
Clear instructions for users
Ease of use is a priority in Zoho Forms. You can provide instructions to guide users through the OTP process, which helps minimize confusion and ensure a smooth experience.
For example, add an instruction saying, “Please enter the OTP sent to your mobile number. Didn’t receive it? Click ‘Resend OTP’."
Consent and transparency
Building trust with users is crucial. Zoho Forms allows you to add consent statements to ensure users understand why their contact information is being used for OTP verification.
OTP verification is not just a security feature—it’s a trust-building tool that enhances user experience and ensures data authenticity. With its thoughtfully designed OTP verification system, Zoho Forms seamlessly combines robust security, user flexibility, and unparalleled ease of use to set a new standard for online form authentication.
