Authentication for builders
SpartanAuth handles MFA, WebAuthn, passwords, and account flows — so you can ship your product instead of debugging login pages.
Stop building auth from scratch
Drop-in web components. Real MFA and WebAuthn. A dashboard for your team. Authentication that just works.
Built for the AI era
Cursor, Copilot, and Bolt are amazing for building fast — but authentication needs security expertise. SpartanAuth gives you that in a drop-in package.

Focused on what matters: secure authentication, great UX, and easy integration.
TOTP authenticator apps, WebAuthn/passkeys, and magic links. Give your users real security without the friction.
Framework-agnostic login, registration, and account management components. Style them with CSS to match your brand.
Password reset, email verification, account recovery — the flows everyone forgets until a user is locked out at 2am.
Manage users, admins, and security policies. See who's logging in, reset credentials, and enforce MFA — all from one place.
Cloud-native, 12-factor compliant. Single binary deployment. Handles thousands of auth requests with minimal resources.
No PhD in security required.
Point your app at your SpartanAuth instance. One API key, one config file.
// That's it. Seriously.
<spartan-login
api-url="https://auth.yourapp.com"
app-id="your-app-id"
/>
Our web components use CSS custom properties. Make them look like your app, not ours.
spartan-login {
--sa-primary: #your-brand-color;
--sa-radius: 8px;
--sa-font: 'Inter', sans-serif;
}
Your users get MFA, passkeys, password reset, and account management. You get to work on your actual product. Everyone wins.
