ChatGPT adds a 30-minute security window

OpenAI’s new ChatGPT Security History puts sign-ins, sign-outs, password changes, and MFA/passkey changes in one account log, but “Log out of all devices” can take up to 30 minutes to terminate other sessions. The OpenAI account-security guide also says enabling MFA does not cancel existing logins. Builders extending OpenAI’s incident-disclosure controls should treat the log as evidence and the 30-minute window as residual-access budget, not proof that a compromised agent is immediately contained.
