rishav001

<p>Rishav AuthNova OTP adds a one-time-password verification layer to core WordPress authentication flows.</p>
<p>Features include:</p>
<ul>
<li>Configurable OTP length and charset (numeric or alphanumeric)</li>
<li>OTP expiry and retry limits with temporary lockouts</li>
<li>Login OTP verification step (after password check)</li>
<li>OTP-gated registration flow</li>
<li>OTP-gated password reset flow</li>
<li>Delivery via wp_mail, SendGrid, and Twilio</li>
<li>OTP storage using hashes (never plaintext)</li>
<li>Resend OTP with cooldown and challenge rotation</li>
</ul>
<p>Security highlights:</p>
<ul>
<li>OTP values are hashed before storage and are never saved as plaintext</li>
<li>OTP hashes use keyed HMAC storage and constant-time verification</li>
<li>OTP challenges expire automatically and enforce retry limits per challenge</li>
<li>Request throttling applies cooldown and exponential backoff per IP and identifier</li>
<li>Lockout windows reduce repeated invalid OTP submissions</li>
<li>Nonces are applied on sensitive form submissions</li>
<li>Public auth responses are intentionally generic to reduce account-enumeration leakage</li>
<li>Delivery uses synchronous-first send with bounded async retry fallback and challenge-level delivery status tracking</li>
</ul>
<p>Security limitations:</p>
<ul>
<li>This plugin does not replace passwords, HTTPS, WAF/rate-limiting at the edge, or secure hosting controls</li>
<li>OTP delivery depends on the configured email/SMS provider uptime and deliverability</li>
<li>Administrators should combine this plugin with standard WordPress hardening and monitoring</li>
</ul>
<p>Reliability notes:</p>
<ul>
<li>OTP delivery is attempted synchronously first to reduce silent failures</li>
<li>If synchronous delivery fails and background delivery is healthy, the plugin schedules bounded retries</li>
<li>If background delivery is unhealthy (for example DISABLE_WP_CRON), fallback queueing is skipped and users receive a retry-safe error</li>
<li>Resend cooldown state is server-authoritative and exposed through a status endpoint used by frontend countdown UX</li>
<li>Background queue payload contains only challenge ID (no raw OTP or destination data)</li>
</ul>
