Overview

Authyo OTP for Met Form adds a one-time-password check to your MetForm forms. Visitors verify their email address or phone number before the form can be submitted, so only real people reach your inbox.

There is nothing to add to the form itself. Build your form as usual with MetForm’s standard Email and Telephone widgets, then switch on Enable OTP for that form in the Forms tab. The plugin finds the fields and adds the OTP steps to them.

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

  • Per-form switch

    Turn OTP on for the forms you choose. Email and phone can be switched on or off separately for each form.

  • Automatic field detection

    The standard MetForm Email and Telephone widgets are found automatically, in MetForm’s builder or in Elementor.

  • 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 channel after a short wait. You can also let them choose a method straight away.

  • Met Form Entries

    Every MetForm submission is saved as a lead, with its verification status: Verified, Skipped or Unverified.

  • Country selector

    Show all countries, selected countries only, or a single country.

  • Setup popup

    A guided popup takes you from credentials to a form with OTP.

  • Fail-safe protection

    If your balance runs out, forms keep working without OTP so you do not lose leads.

Requirements

  • WordPress 6.2 or later and PHP 7.4 or later.
  • MetForm installed and activated.
  • 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 MetForm first, then the Authyo add-on.

  1. Install and activate MetForm

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

  2. Install Authyo OTP for Met Form

    Go to Plugins → Add New, search for Authyo OTP for Met Form, 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 for Met Form item appears in the WordPress admin menu. The settings page has five tabs: General, Verification Methods, Forms, Met Form Entries and Support.

Setup

Connect the plugin to your Authyo account and choose how OTPs are sent. You can use the setup popup (Credentials, Channels, Countries, OTP Behaviour and Form Setup), 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 for Met Form → General. Under API Credentials, enter the Client ID and Client Secret, then save. After saving, each field shows Saved. Leave a field blank to keep the saved value.

    Failsafe: if your Authyo wallet balance runs out, the plugin automatically bypasses OTP verification so your forms keep working.

  4. Choose your OTP channels

    Open the Verification Methods tab. Under Enable OTP Channels, switch on Email, SMS, WhatsApp and Voice Call as needed. For phone channels, your form must include a phone number field. Voice Call is currently available only for India.

  5. Set the phone method and country list (optional)

    Under Phone OTP Settings, choose the Primary Phone OTP Method. Under Country Dropdown Configuration, choose All Countries, Selected Only or Single Country, and set a Default Country.

How to use

OTP is switched on per form in the plugin settings. You do not edit the form.

  1. Build your form as usual

    Create the form with MetForm’s own builder or with Elementor. Use the standard Email and Telephone widgets. Save the form so its fields are stored.

  2. Open the Forms tab

    Go to Authyo OTP for Met Form → Forms. Your MetForm forms are listed with their Email and Phone fields.

  3. Switch on Enable OTP

    Switch on Enable OTP for each form you want to protect. You can switch the Email Field and the Phone Field on or off separately. If a form has both, both are verified by default.

    If a form shows “No Email or Telephone field found in this form”, it has no saved fields yet. Add an Email or Telephone widget in the form editor and click Save. Forms that already use the older Authyo Email or Authyo Phone widgets still work and are detected the same way.

  4. Save and test the form

    Save your settings and open the form on your site. Enter an email address or phone number, request the code, enter it and submit.

The Forms tab warns you if the channel you need is not switched on: for example, that no channel is enabled, that the Email channel is off, or that no phone channel is enabled. In those cases OTP will not run, even when it is switched on for the form.

Troubleshooting

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

The form does not ask for an OTP
Check that Enable OTP is switched on for that form in the Forms tab, that your credentials are saved, and that the right channel is enabled in Verification Methods. Email OTP does not run if the Email channel is off, and phone OTP does not run if no phone channel is on.
The Forms tab says “No Email or Telephone field found in this form”
The form has no saved Email or Telephone field yet. Open it with Edit Form, add the standard Email or Telephone widget, and click Save.
The Forms tab says no channel is enabled
Open Verification Methods and switch on at least one channel. Until then OTP will not run, even if it is switched on for a form.
The OTP does not arrive
Check your Client ID and Client Secret, that the channel is switched on, that your Authyo wallet has balance, and that the email address or phone number is valid. Voice Call works only for India. Visitors can use the fallback options that appear after the timer.
Forms submit without OTP even though it is switched on
If your Authyo wallet balance is empty, the plugin lets submissions through so no leads are lost. Check your balance and top up. Also check whether skipping is allowed for the channel.
The country list is empty
Save your credentials, then open the General tab and click Refresh Country List Now.
I see “Missing security nonce” or a security error
The page was open for a long time, or an old cached copy is being shown. Reload the page. If it keeps happening, exclude the form page from caching.
Some entries show as Unverified
Every MetForm submission is saved, including those from forms that do not use OTP, and an entry shows Unverified when the contact was not verified. To verify visitors on a form, switch on Enable OTP for it in the Forms tab.
The code was wrong or expired
Ask the visitor to check the digits or request a new code. By default a code is valid for 5 minutes. You can raise Expiry (minutes) up to 10.

Frequently asked questions

Does this plugin require MetForm?
Yes. It is an add-on for MetForm and needs it installed and activated.
Do I need an Authyo account?
Yes. You need an Authyo account to get a Client ID and Client Secret for the plugin settings.
How do I set up OTP on a form?
Go to Authyo OTP for Met Form → Forms and switch on Enable OTP for the form. The Email and Telephone fields are detected automatically.
Do I need a special widget?
No. The standard MetForm Email and Telephone widgets work, in MetForm’s builder and in Elementor. The older Authyo Email and Authyo Phone widgets are still supported.
Can I use both email and phone OTP on the same form?
Yes. If a form has both an Email and a Telephone field, both are verified. You can turn either one off for each form in the Forms tab.
What happens if my Authyo balance runs out?
The form still submits without OTP verification, so you never lose a lead because of a billing issue. Top up your Authyo wallet to turn verification back on.
Can visitors skip verification?
Only if you allow it under Verification Methods → Optional Verification. By default verification is mandatory.
Which countries are supported?
The country list comes from Authyo and includes 200+ countries. You can show all countries, a selected few, or a single country.
Is user data stored on my site?
OTP codes are never stored locally. Temporary session data is kept in WordPress transients and expires automatically. Every MetForm submission, with the fields the visitor filled, their verification status and IP address, is saved in a local table so you can review it in the Met Form Entries tab. Entries stay until you delete them, and deleting the plugin removes the table and its entries.
Is this plugin made by the MetForm team?
No. It is developed by Konceptwise Digital Media Pvt. Ltd. and is not affiliated with, endorsed by or supported by MetForm.
