Identity Verification vs MFA

Identity verification confirms that the specific person you intend to reach is the one responding — often for a single high-stakes decision (approve a wire, explain suspicious activity, confirm an access request). MFA (multi-factor authentication) confirms that whoever is signing in can satisfy enrolled factors at login or step-up time.

Key differences

• Intent: Verification ties an outcome to a named individual in a workflow; MFA protects account sessions generically.
• Channel: Verification may use Slack ChatOps, webhooks, or out-of-band links; MFA is typically bound to the app or IdP login flow.
• Impersonation: Deepfake calls, vishing, and session hijack can bypass "someone authenticated" without proving the right person approved the action.
• Response: Verification products like Challenge can trigger session revocation and device containment when verification fails.

MFA remains essential for everyday authentication. Identity verification adds assurance when the question is not "is this a valid login?" but "is this really our CFO approving this payment?"
