Fast, flexible, and usable security
We understand that good security solutions are user-centric, and that low-friction solutions are paramount to usable application security. MFKDF2 securely derives cryptographic keys from multiple authentication factors while achievinguser indistinguishability, meaning that applications become meaningfully harder to attack while users notice no difference at all.
MFKDF2 is fully backward compatible with existing, commonly used factors such as passwords, hardware tokens, and biometrics, ensuring that users don't have to learn new technologies and can continue to use factors they are familiar with.
Learn moreSimple enforcement of complex policies
Between juggling multiple compliance requirements, complex organizational policies, and the need to protect sensitive data, real-world applications demand robust enforcement of complex security policies.
Multifactor's “Switchboard” technology suite uniquely enables trustless enforcement across authentication, authorization, and auditing, transforming typically weak, software-defined enforcement into strong, cryptographically backed guarantees.
Learn moreShare resources effectively
Existing account sharing solutions are often irrevocable, untraceable, and backed by weak password-based cryptography. It's no wonder that major password management solutions have dozens of publicly confirmed data breaches!
Multifactor's “Checkpoint” technology uniquely enables online resources to be shared by multiple users in a way that is immediately revocable, non-repudiable, and fine-grained, without requiring any changes to the underlying application being shared.
