ChatGPT users can now remotely sign out of their account on other devices to manage sessions and check for unauthorized access. To do so on the website, users go to ChatGPT, log in, click their profile icon, and select Settings. On the mobile app, they open ChatGPT and tap their profile icon. In either case, they choose "Security and login" from settings, then look under "Sessions" for "Active Sessions" to view devices. Users can select "Log out" next to any device or click "Log out all" to end all active sessions across all devices, a process that could take as long as 30 minutes and will also log the user out of their current chat session.
