Passkey-first
WebAuthn ceremonies keep reusable passwords out of the core sign-in path.
Deployment stories
One identity boundary.
Different operating realities.
RustyAuth starts as a fast path to passkey authentication for SaaS teams. The same compact boundary can move into customer cloud, installed products and—after further assurance work—disconnected systems.

Different sectors.
The same narrow promise.
Short-lived trust
Revocable sessions and audience-bound tokens limit what moves between systems.
Customer-controlled
Identity state, signing keys and recovery operations stay inside the deployed boundary.
Explicit scope
The protected application—not RustyAuth—owns business permissions and resource decisions.
Open-source core
Start locally.
Decide where trust belongs.
Evaluate the implemented authentication boundary before designing a regulated or disconnected production profile.
