How to Investigate a Possible Account Takeover Without Locking Out the User

A suspicious sign-in requires containment, but broad account shutdown can interrupt critical work before evidence is understood.

Checks to make

Validate sign-in context, factor changes, sessions, and recent account actions. Use targeted session revocation or credential reset under policy, confirm the user through a trusted channel, and preserve audit records. Escalate promptly if privileged access or sensitive data is involved.
