Memorized secrets chosen randomly by the CSP or verifier SHALL be at least 6 characters in length and MAY be entirely numeric.` - The minimum entropy for a randomly chosen memorized secret is approximately 20 bits. - A keypad with 6 keys, each having 9 properties, exceeds this requirement with a minimum 4-character nKode, providing approximately 23 bits of entropy. ### nKode Observation - Cracking an nKode [Evil nKode](https://git.infra.nkode.tech/dkelly/evilkode) - Replay Attack ### Dispersion Attack ### nKode Over low-bandwidth ### nKode Over Unencrypted Channel - TOTP - DARC
