Using CardSpace As A Secure Password Manager

It's 2026. The "Digital Wallet" isn't a feature anymore; it's invisible plumbing. You glance at your phone, a biometric prompt flashes, and you're in. No typing, no friction. We take this magic for granted.
But twenty years ago, Microsoft tried to solve this exact problem with Windows CardSpace.
The software is long dead. Buried. But the architectural concept-using CardSpace as a "Password Manager" rather than just a raw authentication protocol-was a revolutionary idea. It predicted the current state of Identity Management with eerie precision.
