MFA · Compare
Duo adds a second factor. H33 makes the first factor unphishable.
Duo pushes a second-factor prompt on top of a password login. The password is still the failure surface. H33 removes it: sites verify a cryptographic signature, and the biometric that produces it never leaves the device.
Side by side
Where H33 changes the trade.
| Question | Duo | H33 |
|---|---|---|
| First factor | Password (unchanged) | Cryptographic device trust |
| Second factor | Push notification | Same identity signs · no second prompt needed |
| Phishable? | The password still is | No · signature bound to origin |
| Recovery | Vendor + admin | Guardian-based · identity-owned |
| Post-quantum | No | Yes · today |
| AI action authority | Not covered | Bound to authority chain (governed AI authorization) |
