Authyo OTP for Ninja Forms is a specialized integration designed to add secure email verification to your Ninja Forms. 
Prevent spam and fake submissions by ensuring users verify their email address via a one-time password (OTP) before submitting the form. 
This lightweight plugin is focused purely on form-level verification, ensuring no bloat while keeping your forms secure.
This plugin connects to Authyo’s external API service to generate and validate OTPs.
Features:
<ul>
<li>Easy Integration: Adds a custom “Authyo OTP” field to your Ninja Forms builder.</li>
<li>Smart OTP Verification: Enforces OTP validation when Authyo is properly configured and funded.</li>
<li>Customizable Settings: Adjust OTP length, expiry time, and verification options.</li>
<li>Fail-Safe Protection: Automatically allows submissions to continue if Authyo is not configured or the wallet balance is exhausted.</li>
<li>Developer Friendly: Hooks and filters available for advanced customization.</li>
</ul>
Note: OTP verification requires valid Authyo API credentials and sufficient wallet balance. When unavailable, form submissions will proceed without OTP verification.
