The single greatest point of failure in our digital lives is the fragile, outdated password. The UIID system is engineered to eliminate passwords entirely, replacing them with an instantaneous and mathematically guaranteed secure login method: the Cryptographic Challenge/Response Transaction.
This system works for both your high-trust UIID Core and your anonymous UIID Aliases.
Every password you use can be:
Stolen in a data breach.
Guessed through brute force or dictionary attacks.
Fished by sophisticated social engineering scams.
UIID authentication shifts the basis of security from "guessing a secret word" to "proving something mathematically," a process that completely removes the shared secret (the password) from the equation.
The UIID login is a quick, three-second cryptographic handshake between the website and your Identity Vault, based on strong asymmetric key pairs (Public and Private Keys).
Step | Action | Security Principle |
|---|---|---|
1. Request | You click "Login with UIID" on a website. | Simple User Interface |
2. Challenge | The website generates a unique, single-use random piece of data (the Challenge). | Ensures the login cannot be replayed or faked. |
3. Dispatch | The website sends the Challenge to your UIID Identity Vault (usually on your phone or computer). | Secure Communication Channel |
4. Sign | Your Vault uses your unique Private Key (which never leaves your device) to mathematically sign the Challenge. | The only proof of ownership is the Private Key. |
5. Response | The Vault sends the signed Response back to the website. | Secure Communication Channel |
6. Verification | The website verifies the signature using your publicly known key (linked to your Alias or Core DID). | Mathematical certainty. Only your Private Key could have created that specific signature for that specific Challenge. |
The risk of password theft literally drops to zero. Since no shared secrets are ever transmitted, your identity is fortified by an unassailable mathematical process, delivering strong security that is also faster and simpler than typing a password.
