Multi-factor authentication is a strong front-door lock, but it is not the only thing that decides whether someone can get into your accounts. After you sign in, your browser keeps you logged in using a session token, acting just like a digital wristband. โ
If an attacker steals that wristband, they bypass your MFA prompt entirely by replaying your already authenticated session. ๐ป

Since attackers are trying to go around the login step instead of beating it, you must treat device health as a core part of your identity. You also need to tighten session policies for high-risk access, make phishing harder to pull off, and use monitoring that catches suspicious access patterns early.
By implementing these layers, you keep multi-factor authentication as a powerful, solid baseline defense while reducing the real threat of account takeovers.
