HomeCompareH33 vs Duo

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.
