QRAuth

QRAuth replaces the password field on your WordPress login page with a drop-in QR widget. Users sign in by scanning with the QRAuth mobile app; a cryptographic signature is verified server-to-server before WordPress sets the auth cookie. Social login (Google, GitHub, Microsoft, Apple) is brokered by QRAuth’s hosted approval page, so you never have to register an OAuth app or hold a client secret.
One Client ID is the only configuration. Paste it into Settings → QRAuth and the widget appears on wp-login.php. Everything else — the approval flow, the signing, the token refresh — lives in the QRAuth platform.
Account safety is the default. Auto-provisioning is off out of the box: only WordPress users who already exist (matched on email) can sign in via QRAuth. Flip on auto-provisioning and new users are created as Subscriber — that’s the only role available, intentionally and at every layer (settings UI, sanitiser, runtime). Operators who need a different role for an individual user can change it manually via Users → All Users after their first sign-in. The plugin never stores the signing material, never issues a redirect outside your site, and never touches your user table on uninstall.
Self-hosted, no third-party scripts on wp-login.php. The QRAuth web component ships vendored inside the plugin — the only outbound call is from your server to QRAuth’s verification endpoint during a sign-in attempt.
Open source build. The compressed JavaScript at <code>assets/js/qrauth-components.js</code> is built from publicly available TypeScript source at https://github.com/qrauth-io/qrauth/tree/main/packages/web-components. The unminified source files are also vendored alongside the minified bundle inside this plugin (<code>assets/js/source/</code>) for offline review. See the Source section below for build instructions.
<h3>External services</h3>
This plugin connects to QRAuth (https://qrauth.io) — the identity verification service that performs the actual passwordless / social sign-in. QRAuth is operated by ProgressNet, the publisher of this plugin. Without QRAuth there is no widget and no sign-in.
What the service is and what it is used for
QRAuth verifies that the user who scanned the QR code (or completed a social-provider flow on the hosted approval page) is the same person who initiated the sign-in on your WordPress site, then returns a signed assertion that the plugin uses to set the WordPress auth cookie.
What data is sent and when
<ul>
<li>Auth-session creation — when a visitor opens a page that hosts the widget (wp-login.php, the registration form, a shortcode-enabled page, or a WooCommerce sign-in form), the plugin’s same-origin REST proxy sends your Client ID, Client Secret (server-side only — never exposed to the browser), and the host page URL to <code>https://qrauth.io/api/v1/auth-sessions</code>. No visitor data is included in this request.</li>
<li>Sign-in verification — when the visitor approves the sign-in (by scanning with the QRAuth mobile app or completing a social-provider flow on QRAuth’s hosted approval page), the plugin’s REST proxy fetches the verified result from <code>https://qrauth.io/api/v1/auth-sessions/verify-result</code>. The response carries the QRAuth user identifier and, when the <code>email</code> scope is allowed in Settings → QRAuth, the user’s email address. The plugin uses this only to locate or create the matching WordPress user; nothing beyond a hashed link reference is retained.</li>
<li>Hosted approval page — when a visitor on a phone taps “Continue with QRAuth”, the browser navigates to <code>https://qrauth.io/a/<token></code> to complete the social-provider flow. This is a standard cross-domain navigation initiated by the visitor.</li>
</ul>
The vendored web component (<code>assets/js/qrauth-components.js</code>) is served from your own WordPress site — there is no third-party JavaScript on wp-login.php, and the component does not contact qrauth.io directly from the browser; all server-to-server calls are proxied via your site’s REST API.

The unminified TypeScript source files are also vendored alongside the compiled bundle inside this plugin (<code>assets/js/source/</code>) for offline review.
The plugin’s own source — PHP, the small browser adapter (<code>assets/js/qrauth-adapter.js</code>), build scripts, tests, and CI — is publicly maintained under GPL-2.0-or-later at:
<ul>
<li>Plugin source repository: https://github.com/qrauth-io/qrauth-passwordless-social-login</li>
</ul>
The PHP and <code>assets/js/qrauth-adapter.js</code> shipped in the plugin ZIP are non-minified — read them directly without checking out the repo.
The vendored file <code>assets/js/qrauth-components.js</code> is a pinned production build of the public <code>@qrauth/web-components</code> library. The non-compiled source for that library is openly available:
<ul>
<li>Source repository: https://github.com/qrauth-io/qrauth/tree/main/packages/web-components (MIT-licensed)</li>
<li>npm release: https://www.npmjs.com/package/@qrauth/web-components — pinned to v0.4.1, sha512 in <code>package.json</code> under the <code>qrauth.webComponentsIntegrity</code> key</li>
<li>Build instructions for the upstream library: https://github.com/qrauth-io/qrauth/blob/main/BUILDING.md</li>
</ul>
To regenerate the vendored bundle from the pinned npm release, clone the plugin source repository linked above and run from its root:
<pre><code>npm install
npm run build:assets
</code></pre>
The build script <code>bin/fetch-web-components.mjs</code> (kept in the plugin source repository, not in the WordPress.org plugin ZIP) downloads the npm tarball, verifies its sha512 SRI hash against <code>package.json#qrauth.webComponentsIntegrity</code>, extracts the IIFE build, and writes it to <code>assets/js/qrauth-components.js</code>. CI runs the same script before the WordPress.org plugin-check job, so the bundle distributed on the directory always matches the published npm release. To rebuild from upstream source instead of the pinned tarball, follow <code>BUILDING.md</code> in the upstream library repository above.

QRAuth – Passwordless & Social Login

Passwordless sign-in for WordPress. Users scan a QR code with the QRAuth mobile app — no passwords, no forms, no OAuth apps to register.

<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.
