Could a stolen session bypass the password and multi-factor authentication?¶

Yes. If an attacker copies or replays a valid session cookie or token, the service may treat the request as already authenticated and require neither the password nor a new multi-factor challenge.

Authentication can precede the misuse¶

A legitimate login creates session artefacts that allow later requests. The original authentication and malicious use may occur at different times, from different networks or through different clients. Login history can therefore look normal even while an existing authenticated state is being misused.

Preserve session IDs, token issue and refresh events, application and browser information, IP changes, resource activity and revocation records. Compare them with local browser artefacts, phishing history, malware evidence and physical or remote device access.

Interpret discontinuities carefully¶

The same session appearing across incompatible devices or distant locations may support token theft, but provider routing, mobile networks and legitimate session hand-off must also be considered. A changed address alone does not establish a stolen session.

A password reset may not revoke every token or application session. Confirm whether the provider invalidated the relevant session family, refresh token and connected applications, and when later requests began to fail.
