Operational resilience
Authentication should not become unavailable solely because a public identity service or external network path is down.

For banking and payment systems
Customer-controlled authentication for sensitive access.
RustyAuth can become a compact authentication component beside a banking product—not a claim to replace the institution’s identity, fraud or transaction controls.

The operating reality
A banking software provider protecting a sensitive workflow
The provider needs phishing-resistant customer or workforce access while preserving the bank’s control over identity state, signing keys and operational recovery. RustyAuth sits inside the institution’s environment and issues short-lived claims to the application, while the bank’s policy and risk systems decide what each authenticated person may do.
Credential risk
Phishing-resistant credentials reduce reliance on passwords and manually entered one-time codes.
Institutional control
Keys, audit evidence, recovery and deployment lifecycle must fit established governance boundaries.
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.
Local verification
WebAuthn ceremonies are verified inside the deployed RustyAuth boundary.
Short-lived claims
Audience-bound access tokens narrow the trust passed to banking applications.
Key lifecycle
Staged signing-key rotation with overlapping public-key publication.
Honest boundary
What this story does—and does not—claim.
Regulated infrastructure earns trust through evidence. These boundaries remain explicit in the 1.0.0 GA contract.
RustyAuth does not replace
- Transaction signing or payment approval
- Fraud and risk engines
- KYC or AML controls
- Core banking authorisation
Production profile requires
- HSM-backed server keys
- Qualified high availability
- Dual-control administration
- Enterprise federation and independent assessment
