What Is MFA Fatigue?

MFA fatigue is an attack in which a threat actor repeatedly sends multifactor authentication prompts to a user after obtaining or guessing the user’s password. Certification questions may describe numerous unexpected approval requests and ask candidates to identify the attack or select the strongest mitigation. The attacker expects the user to approve a prompt accidentally, out of frustration, or because a convincing phone call or message claims the request is legitimate. Number matching, contextual login details, limited prompt frequency, user reporting options, and phishing-resistant authentication methods reduce this risk. Users should deny unexpected requests and report them immediately rather than simply ignoring repeated prompts. Security teams should investigate the originating login attempts, reset compromised credentials, revoke sessions, review account activity, and determine whether the attacker achieved access.
