<p><strong>Sparrow Email OTP Verification for Contact Form 7</strong> provides a robust security layer for your website by verifying user email addresses before form submission. This effectively blocks bots, spammers, and malicious actors from flooding your inbox with fake data or invalid leads.</p>
<h3>Why this plugin is different:</h3>
<p>Most existing OTP plugins require you to pay for their proprietary API or use their specific SMTP service to send codes. This often leads to unexpected monthly costs and vendor lock-in.</p>
<p>This plugin is built with a <strong>“Your Server, Your Rules”</strong> philosophy. It sends OTP codes using the native <code>wp_mail()</code> function, meaning it utilizes your website’s default mail configuration or your preferred SMTP service. <strong>There are no extra costs, no hidden fees, and no third-party accounts required.</strong></p>
<h3>Features</h3>
<ul>
<li><strong>Block Bots & Spam:</strong> Ensure every submission comes from a person with a valid, accessible email address.</li>
<li><strong>Conditional Display (New v1.1.0):</strong> Dynamically hide verification elements inside an elegant wrapper box until an email string is typed.</li>
<li><strong>Cost-Effective:</strong> Zero cost to send OTPs—it uses your existing server or SMTP setup.</li>
<li><strong>Privacy First:</strong> No data is sent to external verification APIs; everything stays on your server.</li>
<li><strong>Smart Detection:</strong> Automatically finds the email field in your Contact Form 7 forms.</li>
<li><strong>Security-First Rate Limiting:</strong> Built-in protection to prevent OTP request abuse by limiting users to 3 attempts per 5 minutes per IP address.</li>
<li><strong>Lightweight:</strong> Minimal footprint to ensure your site remains fast and passes Core Web Vitals.</li>
</ul>

<p>Authyo OTP for MetForm lets you add One-Time Password (OTP) verification to any MetForm form in seconds. Protect your forms from spam and fake submissions by verifying real email addresses and phone numbers before the form is submitted.</p>
<h4>Why Use OTP Verification?</h4>
<ul>
<li><strong>Reduce spam and fake leads</strong> — only verified users can submit forms.</li>
<li><strong>Improve data quality</strong> — ensure the email and phone number entered are real and accessible.</li>
<li><strong>Build trust</strong> — visitors know their information is being handled securely.</li>
</ul>
<h4>How It Works</h4>
<ol>
<li>Install the plugin and enter your Authyo API credentials.</li>
<li>Drag the <strong>Authyo Email</strong> or <strong>Authyo Phone</strong> widget into your MetForm form using Elementor.</li>
<li>That’s it — OTP verification activates automatically on any form that contains an Authyo widget.</li>
</ol>
<p>No extra toggles, no per-form configuration. Just add the widget and it works.</p>
<h4>Supported Verification Channels</h4>
<ul>
<li><strong>Email</strong> — OTP delivered to the visitor’s email inbox.</li>
<li><strong>SMS</strong> — OTP delivered via text message to the visitor’s phone.</li>
<li><strong>WhatsApp</strong> — OTP delivered via WhatsApp message.</li>
<li><strong>Voice Call</strong> — OTP delivered via automated voice call (currently available in India).</li>
</ul>
<h4>Key Features</h4>
<ul>
<li><strong>Multi-Channel Verification:</strong> Deliver OTPs via SMS, WhatsApp, Voice Call, or Email.</li>
<li><strong>Zero-Config Integration:</strong> Automatically activates on any MetForm that contains an Authyo widget — no per-form enable toggle needed.</li>
<li><strong>Visitor Choice:</strong> Optionally allow visitors to choose their preferred verification method.</li>
<li><strong>Fallback Methods:</strong> If the primary method doesn’t work, visitors can try an alternative channel (e.g., switch from SMS to WhatsApp).</li>
<li><strong>Skip Verification:</strong> Optionally allow visitors to skip OTP for specific channels.</li>
<li><strong>Country Dropdown:</strong> Configurable country selector with All Countries, Selected Only, or Single Country modes.</li>
<li><strong>Failsafe Behavior:</strong> If the Authyo API cannot deliver OTP messages due to insufficient balance, the plugin automatically allows form submission to prevent lead loss.</li>
<li><strong>Customizable Security:</strong> Configure OTP length (4-8 digits), expiry time (1-10 minutes), resend cooldowns, and max resend attempts.</li>
<li><strong>Lead Management:</strong> View all form submissions with verification status (Verified, Skipped, Unverified) directly in WordPress admin.</li>
</ul>
<p><strong>Important Note:</strong> OTP verification requires valid Authyo API credentials and sufficient wallet balance. When unavailable, form submissions will proceed without OTP verification to prevent lead loss.</p>
