From an operational security standpoint, managing SSO involves constant vigilance against session hijacking and token replay. WWPass’s architecture, rooted in cryptographic proof rather than transferable tokens, appears to offer superior resistance to these vectors. My current focus is on how their system manages the lifecycle of the single, persistent identity proof across multiple application invocations without introducing replay risks. If the authentication mechanism is tied directly to the integrity of the client hardware at the moment of access, it inherently provides a more dynamic and verifiable form of “single sign-on” than any system reliant on exchanging transferable session cookies or opaque access tokens. It elevates the client device itself to the role of the ultimate, unforgeable authenticator.
