Overview

Authyo OTP for SureForms adds a one-time-password check to your SureForms forms. Visitors verify their email address or phone number before the form can be submitted, which reduces spam and fake submissions.

You add OTP with a form block. In the SureForms editor, add an Authyo Email, Authyo Phone or Authyo Smart Field block to your form, then publish it as usual.

This plugin is an independent add-on for SureForms, developed by Konceptwise Digital Media Pvt. Ltd. It is not affiliated with, endorsed by or supported by SureForms.

  • Three Authyo blocks

    Verify an email address, a phone number, or let the visitor enter either one in a single smart field.

  • Four OTP channels

    Email, SMS, WhatsApp and Voice Call. Voice Call is currently available in India only.

  • Fallback methods

    If the code does not arrive, visitors can try another way after a short wait. You can also show every channel as a button from the start.

  • Multi-page forms

    Optionally stop visitors from moving to the next page until the Authyo fields on the current page are verified.

  • Lead Management

    See every submission captured by OTP, set its status, filter, search and export to CSV.

  • Country selector

    Choose all countries or only the ones you serve.

  • Setup popup

    A guided popup takes you from credentials to a form embedded on a page.

  • Fail-safe protection

    If Authyo is not configured or your balance is used up, submissions continue without OTP, so no leads are lost.

Requirements

  • WordPress 5.5 or later and PHP 7.4 or later.
  • SureForms installed and activated. The plugin shows a “SureForms Plugin Required” notice with an install button if it is missing.
  • An Authyo account with an application. You will need its Client ID and Client Secret.
  • Balance in your Authyo wallet to send OTPs.

Installation

Install SureForms first, then the Authyo add-on.

  1. Install and activate SureForms

    Go to Plugins → Add New, search for SureForms, then click Install Now and Activate. Skip this step if it is already active.

  2. Install Authyo OTP for SureForms

    Go to Plugins → Add New, search for Authyo OTP for SureForms, then click Install Now and Activate. You can also upload the plugin ZIP using Plugins → Add New → Upload Plugin.

  3. Open the plugin settings

    A new Authyo OTP item appears in the WordPress admin menu. The settings page has five tabs: General, Verification Methods, How to Use, Support and Lead Management.

Setup

Connect the plugin to your Authyo account and choose how OTPs are sent. You can use the setup popup, which has six steps (Credentials, Channels, Countries, OTP Behaviour, Form Setup and Embed on Page), or fill in the tabs yourself.

  1. Create your Authyo account

    Go to app.authyo.io and create a free account.

  2. Copy your credentials

    Open your applications in the Authyo dashboard and copy the Client ID and Client Secret. Create an application first if you do not have one.

  3. Paste them into the General tab

    In WordPress go to Authyo OTP → General. Under API Credentials, enter the Client ID and Client Secret, then click Save Changes. Use the eye icon to show or hide the secret.

    Failsafe: if your Authyo wallet balance runs out, the plugin automatically bypasses OTP verification so your forms keep working and visitors are not blocked.

  4. Choose your verification channels

    Under Verification Channels, switch on Email, SMS, WhatsApp and Voice Call. At least one is required. Pick a Primary Channel (Phone). Voice Call is currently available only for India.

  5. Set the country list (optional)

    Under Country Selection, choose Select All Countries or Select Specific Countries.

How to use

OTP is added with a form block, not a shortcode.

  1. Create or edit a form

    Go to SureForms → Add New, or open an existing form.

  2. Add an Authyo block

    In the form editor, add the Authyo Email block to verify an email address, the Authyo Phone block to verify a phone number, or the Authyo Smart Field block for a single field that accepts an email address or a phone number.

  3. Publish and embed the form

    Publish the form and embed it on a page with the SureForms block or shortcode. The setup popup can also create a page and add the shortcode for you.

  4. Test the form

    Open the page, enter an email address or phone number, click Send OTP, enter the code you receive and submit. If a visitor submits without verifying, they see “Please send and verify the OTP to continue”.

The plugin’s own How to Use tab also says the OTP interface is added to SureForms’ standard Email and Phone blocks while the plugin is active. For predictable results, use the Authyo blocks, which are built for OTP.

Troubleshooting

Most problems have a quick fix. Find your issue below.

I see “SureForms Plugin Required”
The add-on needs SureForms. Click Install SureForms, or install and activate it from Plugins → Add New, then return to the settings.
I do not see the Authyo blocks in the form editor
Check that SureForms and the Authyo plugin are both active, then reload the form editor and search the block list for “Authyo”.
The OTP does not arrive
Check that your Client ID and Client Secret are correct, that your Authyo wallet has balance, that the channel is switched on under Verification Channels, and that the email address or phone number is valid. Voice Call works only for India.
The form submits without asking for an OTP
If Authyo is not configured, or your Authyo wallet balance is empty, the plugin skips OTP so forms keep working. Check your credentials and top up your Authyo wallet. Also check whether skipping is allowed for the channel.
Visitors see “Please send and verify the OTP to continue” or “Please enter the OTP to continue”
The visitor must request the code and enter it before submitting. If you would rather let them skip, switch on Allow skipping email verification or Allow skipping phone verification.
Visitors see “Invalid OTP”
The code was wrong. Check the digits and try again, or request a new code.
Visitors see “Invalid email address” or “Invalid mobile number”
The contact detail is not in a valid format. For phone numbers, choose the right country and check the digits.
Visitors see “Voice Call is not available in the selected country”
Voice Call works only for India. Ask the visitor to choose SMS or WhatsApp, or switch off Voice Call under Verification Channels.
A multi-page form will not move to the next page
Strict Validation (Multi-page Forms) is on, so the Authyo fields on the current page must be verified first. Verify the code, or switch the option off.
The code expired
By default a code is valid for 5 minutes. Ask the visitor to request a new one, or raise Expiry (minutes) (up to 10).
The country list is empty
Check your credentials, then open General → Country Selection and click Refresh Cache.
