After sign-in, applications use session tokens to recognize a user. If an attacker steals or abuses a valid token, they may access the account without knowing the password.
Why it matters
What business leaders should understand
MFA is essential but may not stop every session-theft technique. Device security, phishing resistance, conditional access, application design, and rapid token revocation matter.
The right response should reflect your environment, data, vendors, risk, and operational priorities. Use this guide as a practical starting point, then validate important decisions with the people responsible for your technology, cybersecurity, legal obligations, and insurance coverage.
