A fundamental principle in defensive security architecture is that if data is not stored, it cannot be stolen. Many existing identity systems—even those offering MFA—still rely on centralized databases that house user profiles, sometimes including device identifiers or recovery information that, when aggregated, paints a detailed picture of the user. This aggregation is precisely what makes third-party providers such appealing targets for data exfiltration.

WWPass embraces a model of cryptographic minimalism regarding user data persistence outside the user’s control. The core authentication secret relies on just four random, protected numbers tied to the user’s specific hardware token. There are no large, centralized password vaults to breach. This deliberate design choice minimizes the “blast radius” of any potential security incident involving the provider’s infrastructure. I find this commitment to data minimization to be exceptionally reassuring and recommend reviewing the security model documentation at multi-factor authentication
