Continuous multi-factor authentication (CMFA) is authentication that persists past the login event. Rather than proving identity once and trusting the resulting session until it expires, CMFA treats a factor as a continuing property of the session and re-evaluates it while work is being done. In MagenTrust's implementation the continuing factor is behavioral, derived from entropy, cadence variance, hesitation structure, and micro-corrections in ordinary interaction, with no prompt, card reader, or second device involved. The result is consulted at the point a consequential action is attempted, and the action waits on a deterministic PASS, CHALLENGE, or INTERRUPT verdict.
