MFA Logs: Design an Authentication Audit Trail
Build an MFA audit trail that explains challenges, decisions, enrollment, and recovery while keeping authentication secrets out of the record.
THE SIGNAL / TOPIC THREAD
Authentication.
A thread worth following.
Preserve evidence around sign-in and factor decisions without retaining credentials or treating every successful step as a completed session.
A useful reading path
Read the MFA audit guide for the distinction between attempts, challenges, verification, and session issuance. The MFA topic page offers a concise field reference for building an investigation-ready event contract.
