Standards-based

Everything you need to ship auth

Stop building authentication from scratch. AuthNex provides every piece you need, secured by default.

Multi-Tenant by Default

Isolated user pools, roles, and API keys per tenant. Self-service signup with plan-based limits.

Social Login

Google, Microsoft, and GitHub OAuth built in. Tenants can bring their own credentials for branded consent screens.

Passkeys / WebAuthn

Passwordless authentication with platform authenticators. Register, authenticate, and manage multiple passkeys per user.

TOTP Two-Factor Auth

RFC 6238 compliant TOTP with backup codes. Uses async crypto.subtle for proper HMAC-SHA1.

SCIM 2.0 Provisioning

Enterprise IdP user sync via standard SCIM protocol. Auto-create, update, and deactivate users.

RBAC & Permissions

Flexible role-based access control with custom permissions. System roles plus tenant-scoped roles.

JWT & OIDC

RS256-signed JWTs, JWKS endpoint, and OpenID Connect discovery. Standard token refresh flows.

Custom Branding

Per-tenant logo, colors, and app name. SDK widget automatically fetches and applies your branding.

Audit Logs & Analytics

Full audit trail for every auth event. Analytics dashboards for login trends, anomalies, and security insights.

Integrate in minutes

Add authentication to any app with a few lines of code.

Drop-in JavaScript Widget

One script tag. Embeddable login form with social buttons, passkey support, and auto-branding — no backend changes needed.

PHP SDK

Composer package with token verification, user management, and middleware — works with Laravel, Symfony, and vanilla PHP.

// Drop-in widget — 2 lines
<script src="https://auth.yourapp.com/widget.js"></script>
<div id="authnex-login"
     data-tenant="my-company"></div>

// Or use the PHP SDK
use AuthNex\Client;

$auth = new Client('your-api-key');
$user = $auth->verifyToken($_COOKIE['token']);

if ($user->hasPermission('admin:read')) {
  // Authorized
}
