Multi-Factor Key Derivation Function (MFKDF)
Description: The Multi-Factor Key Derivation Function (MFKDF) is a function that takes multiple inputs and outputs a string of bytes that can be used as a cryptographic key. It serves the same purpose as a password-based key derivation function (PBKDF), but is stronger than password-based key derivation due to its support for multiple authentication factors, including HOTP, TOTP, and hardware tokens like YubiKey. MFKDF also enables self-service account recovery via K-of-N (secret-sharing style) key derivation, eliminati
Password-derived keys are only as strong as the passwords they're based on. Securely leverage all of your users' authentication factors with MFKDF.
