OneCode Login provides a modern, passwordless authentication experience for your WordPress site. Instead of traditional passwords, users receive a secure 6-digit verification code via email.
<h4>Key Features</h4>
<ul>
<li>Passwordless Authentication – Users log in with just their email address</li>
<li>6-Digit Verification Codes – Secure, time-limited codes sent via email</li>
<li>Rate Limiting – Built-in protection against brute force attacks</li>
<li>Request ID Binding – Each code is bound to a specific login session for enhanced security</li>
<li>Neutral Feedback – Prevents user enumeration attacks by not revealing if an email exists</li>
<li>Customizable – Configure expiry times, cooldowns, and email templates</li>
<li>Accessible – Full keyboard navigation and screen reader support</li>
<li>Gutenberg Block – Easy to add login forms to any page</li>
<li>Shortcode Support – Use [onecode_login] anywhere</li>
<li>wp-login.php Integration – Optionally replace the default WordPress login</li>
<li>Developer API – Other plugins can use OneCode Login as an email one-time-code (OTP) service to verify a visitor’s email — see the Developer information section</li>
</ul>
<h4>Security Features</h4>
<ul>
<li>Cryptographically secure code generation</li>
<li>Codes and magic-link tokens are stored HMAC-hashed, never in plain text</li>
<li>Configurable code expiry (default: 10 minutes)</li>
<li>Resend cooldown to prevent spam</li>
<li>IP-based and email-based rate limiting</li>
<li>Automatic lockout after failed attempts</li>
<li>Codes are single-use and invalidated after successful login</li>
</ul>
<h4>Use Cases</h4>
<ul>
<li>Membership sites where password fatigue is an issue</li>
<li>Customer portals requiring simple authentication</li>
<li>Internal tools where security without complexity is needed</li>
<li>Any site wanting to improve user experience</li>
</ul>
<h3>Developer information</h3>
Other plugins on the same site can use OneCode Login as a generic email 
one-time-code (OTP) service — for example to verify a guest’s email before 
letting them act. OneCode emails the code and verifies it; your plugin keeps 
full control of its own login/session (OneCode only asserts that the code is 
valid for the email — it never logs anyone in). It works for any email 
address; the address does not need a WordPress account.
All entry points are plain functions (and matching filters), so you do not need 
a hard dependency on any class. The API is gated by the Settings → Advanced → 
Enable developer API toggle.
Detect support (side-effect free — never call the request hook just to probe):
<pre><code>if ( function_exists( 'onecode_login_request_otp' ) && onecode_login_supports( 'otp' ) ) { ... }
</code></pre>
<ol>
<li>
Start authentication — email a code and receive a handle:
$handle = onecode_login_request_otp( $email, array( ‘consumer’ => ‘my_plugin’ ) ); 
// $handle = array( ‘request_id’, ‘auth_secret’, ‘expires_in’ (seconds), ‘expires_at’ (UTC), ‘sent’ ) 
// On failure: a WP_Error (codes: disabled, invalid_request, rate_limited, cooldown).
</li>
</ol>
Keep <code>request_id</code> and <code>auth_secret</code> server-side (e.g. in a transient tied to the 
visitor). The <code>auth_secret</code> is NEVER shown to the customer — it is what stops an 
outsider who only knows the email from completing verification by guessing codes.
<ol>
<li>
Complete authentication — the customer gives your plugin the code from the email:
$result = onecode_login_verify_otp( array( 
 ’email’ => $email, 
 ‘request_id’ => $handle[‘request_id’], 
 ‘code’ => $code_from_customer, 
 ‘auth_secret’ => $handle[‘auth_secret’], 
 ‘consumer’ => ‘my_plugin’, 
) ); 
// Success: array( ‘valid’ => true, ’email’ => … ). Failure: WP_Error.
</li>
</ol>
On failure show a generic message to the user (the API intentionally returns a 
single <code>verify_failed</code> code so it can’t be used as an oracle).
Filters are also available for loose coupling: <code>onecode_login_request_otp</code> 
(<code>$pre, $email, $args</code>) and <code>onecode_login_verify_otp</code> (<code>$pre, $args</code>).
Discovery and capabilities:
<ul>
<li><code>onecode_login_supports( $feature )</code> — returns true for <code>'otp'</code>, 
 ‘identity_assertion’ and <code>'any_email'</code>.</li>
<li><code>onecode_login_api()</code> — returns the <code>OneCode_Login_API</code> service instance.</li>
<li><code>OneCode_Login_API::VERSION</code> — the API contract version (independent of the 
plugin version), so you can feature-gate against the API surface.</li>
<li><code>do_action( 'onecode_login_api_init', $api )</code> — fires once the API is ready; 
bind to it if you want to wire up as soon as OneCode Login loads.</li>
</ul>
Reference: <code>$args['consumer']</code> (a short <code>[a-z0-9_-]</code> label identifying your 
integration) is required on both calls — it isolates your codes and rate limits 
from the built-in login and from other consumers. Both request and verify are 
rate-limited by OneCode, returning <code>rate_limited</code> / <code>cooldown</code> WP_Errors you can 
surface to the user.

OneCode Login

Simple and secure passwordless login using email verification codes. No passwords to remember, just enter your email and verify with a 6-digit code.

WP Ventra

VentraConnect provides a unified login system for WordPress: Social Login + Magic Link + Email OTP.
<ul>
<li>Social Login with 15+ providers (Google, Facebook, X/Twitter, LinkedIn, Microsoft, GitHub, and more)</li>
<li>Passwordless Login with Magic Link and Email OTP
<ul>
<li>Can run in Login only mode (existing users) or Login & Register mode (allow new accounts)</li>
</ul>
</li>
<li>Guardrails (optional): prevent spam accounts by letting Social Login, Magic Link and Email OTP log existing users in, but optionally blocking them from creating new users. This stops random visitors from turning your login screen into an open registration form, while your normal WordPress registration and any custom onboarding forms continue to work as usual.</li>
</ul>
Works out-of-the-box on the default WordPress login/registration screens (<code>wp-login.php</code>) and also supports shortcodes for custom pages and page builders.
No proxy servers. No third-party tracking. VentraConnect connects directly to each provider using official OAuth flows.

<h3>Roadmap: Passkeys for WordPress</h3>
VentraConnect is being developed as a modern WordPress login suite that currently includes Social Login, Magic Link, Email OTP and Guardrails.
We are also working toward passkey support as a future VentraConnect add-on. The goal is to bring passkey login into the same ecosystem, with fallback options through Magic Link and Email OTP instead of forcing passkey-only access.

<h3>Supported Social Providers</h3>
Google, Facebook, X (Twitter), LinkedIn, Microsoft, GitHub, Discord, Reddit, Slack, Twitch, Spotify, TikTok, Amazon, Yahoo, WordPress.com, LINE.
<h3>How It Works</h3>
<ol>
<li>The user clicks a Social Login button, or requests a Magic Link / Email OTP.</li>
<li>For Social Login, the user authenticates with the provider via official OAuth; for Magic Link / OTP, they verify ownership of their email address.</li>
<li>VentraConnect receives basic profile or email data and looks for an existing WordPress user.</li>
<li>If the email matches an existing user, the login methods are linked to that account and the user is logged in. If not, a new user may be created (subject to your Guardrails and registration settings).</li>
</ol>
<h3>External Services</h3>
VentraConnect Social Login is an OAuth client only.
During login:
<ol>
<li>The user is redirected to the selected provider such as Google or Facebook.</li>
<li>The provider authenticates the user.</li>
<li>The provider returns an authorization token to your site.</li>
<li>VentraConnect retrieves basic profile data:
<ul>
<li>Provider user ID</li>
<li>Email address</li>
<li>Display name</li>
<li>Avatar URL</li>
</ul>
</li>
</ol>
No user data is sent to or stored on servers owned by the plugin author. 
All communication happens directly between your WordPress site and the provider official APIs.
