Ship without the auth detour
Avoid assembling ceremonies, cookie policy, token signing and credential lifecycle code across the product.

For SaaS product teams
Authentication that moves at product speed.
RustyAuth packages WebAuthn ceremonies, durable sessions, token issuance and key operations behind one narrow service boundary.

The operating reality
A product team preparing for its next stage of growth
The team wants phishing-resistant sign-in now, but does not want authentication logic spread across the application or customer identity locked into a mandatory hosted provider. It starts with a local deployment, integrates through explicit HTTP and gRPC contracts, and keeps the option to run the same boundary in customer-controlled infrastructure later.
Reduce reusable secrets
Give people a passkey-first path instead of making passwords the permanent centre of the account model.
Preserve deployment choice
Keep a route from a normal cloud deployment to customer cloud, on-premises or isolated installations.
What the core contributes
Authentication stays small.
The product stays authoritative.
RustyAuth establishes who authenticated and issues narrow claims. Sector-specific systems keep every business decision.
Passkey ceremonies
Server-side, five-minute and single-use registration and authentication state.
Revocable sessions
HttpOnly browser sessions with idle and absolute expiry.
Narrow tokens
Short-lived ES256 access tokens with explicit issuer, audience and tenant claims.

Production profile requires

- Stable migration policy
- Independent security assessment
