Passwordless PAM for a Sacramento Credit Union
How a Sacramento credit union beat an FTC Safeguards deadline by deploying AuthNull — securing 250 users and eliminating passwords as an attack vector.
“We chose to implement AuthNull to meet FTC safeguards and protect our critical infrastructure.”
— Introduction
Securing the Modern Enterprise with Passwordless Access
Organizations face mounting pressure to strengthen security without slowing users down. Password-based authentication — long the default — is now a liability: easy to compromise, expensive to manage, and frustrating to use.
This case study documents how AuthNull helped a Sacramento credit union replace that liability with a passwordless infrastructure layer — meeting a hard compliance deadline while improving security and user experience in the process.
— Background
A Legacy Infrastructure Under Pressure
The client operated across a fragmented stack — legacy on-prem systems, Active Directory, and cloud environments — with no consistent path to strong authentication. Credentials were scattered across systems, difficult to rotate, and easy to forget. Every shared password was a potential entry point, and the FTC Safeguards Rule set a hard deadline to fix it.
Centralised credential stores concentrate risk: when breached, the blast radius is severe. AuthNull’s approach eliminates that surface entirely — no vault to exfiltrate, no passwords to rotate. Each authentication is cryptographic, device-bound, and leaves no credential behind.
— Interoperability & Portability
One Identity Across Every Platform
Credit union staff worked across VPNs, servers, databases, and internal tools — each demanding separate credentials. Identity silos meant separate accounts, separate resets, and compounding helpdesk load. AuthNull’s identity layer unified those surfaces into a single portable identity that works across every endpoint.
With one portable identity, staff authenticate once and navigate every authorised system — no redundant logins, no credential juggling, and no door left open to credential-stuffing attacks.
— Implementation
From Assessment to Full Deployment
AuthNull deployed a tailored passwordless solution across three structured phases, from initial discovery through full production rollout:
Assessment and Planning
We mapped the client's full infrastructure footprint — every legacy system, access pattern, and privilege boundary. This gave us a precise picture of what needed to be secured before a single config was changed.
Solution Design and Integration
We designed a passwordless solution that plugged directly into existing systems — no rip-and-replace. MFA, biometrics, and device trust were layered in without disrupting day-to-day operations.
Pilot Deployment
A controlled pilot with a subset of users validated the solution before full rollout. Feedback was collected, edge cases were handled, and the deployment was tuned — all before the compliance deadline.
— Benefits Gained
What the Organisation Gained
Within weeks of full deployment, the results were measurable across every dimension the organisation cared about:
Enhanced Security
Passwords eliminated — and with them, credential stuffing, phishing, and shared-secret exposure. MFA and biometric verification closed every password-based attack vector.
Improved Productivity
No passwords to remember, reset, or rotate. Support tickets dropped sharply, and IT teams reclaimed hours previously lost to credential management.
Streamlined User Experience
A fingerprint scan or push notification is all it takes. Staff access every authorised system in seconds — adoption was immediate and friction was near zero.
Cost Savings
Helpdesk volume for password issues dropped to nearly zero. The savings in support time and security incident response returned over $1M to the organisation’s budget.
— Conclusion
A Model for Compliance-Driven Security
The credit union didn’t just meet its FTC Safeguards deadline — it built a security posture that will outlast any single compliance requirement. By removing passwords from the equation entirely, the organisation eliminated its most exploitable attack surface and simultaneously improved the day-to-day experience for every user on the platform.
The outcome demonstrates a principle that AuthNull is built on: strong security and frictionless access are not a trade-off. When authentication is cryptographic, device-bound, and seamless, organisations get both — and the compliance paperwork becomes a by-product, not the goal.
— Metrics
Credit Union quickly implemented AuthNull and met all aspects of multifactor requirements as part of the FTC Safeguards rule.
