Memorized Secret Memorized secrets SHALL be at least 8 characters in length if chosen by the subscriber. 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.
