Two lists on Settings → Security show who can act as you right now: Signed-in devices (every browser where your login is open) and Connected apps (AI assistants and other apps you have authorised). Check them after using a shared computer, losing a laptop, or when something in the audit log looks wrong.
These lists cover your own login only. Each team member sees and manages their own.
Sign out one device
- Open Settings → Security and find Signed-in devices. Each row shows the browser and system (for example "Chrome on macOS"), the IP address and when it was last active. The browser you are using is marked This device.
- On the row you want to end, choose Sign out.
The page says That device has been signed out. Whoever was using that browser has to sign in again with your password, and your second factor if you have set one up.
You can't sign out the browser you are using from this list; use the normal sign-out for that.
Sign out every other device
Caution: every browser except this one is signed out at once, including your own phone or work computer. Browsers that were set to remember you are signed out too.
- Open Settings → Security. Above Signed-in devices, choose Sign out all other devices. The button only appears when another device is signed in.
- Choose Sign out other devices to confirm. You stay signed in here.
The page tells you how many devices were signed out.
If you think someone else knows your password, change it as well: Change password on the same page. Then check that your two-factor sign-in and passkeys are the ones you expect.
Note: signing out devices does not touch API tokens or connected apps. Deal with those separately, below.
Disconnect an AI assistant or app
Connected apps on the Security page lists every app you have authorised to act as you, such as Claude, ChatGPT or another MCP client, with the permissions (scopes) it holds and when you authorised it. You manage them on the AI agents page.
Caution: the app stops working with your account straight away. To use it again, you have to connect and approve it again.
- Under Connected apps, choose Manage. This opens AI agents at Connected assistants.
- Open the menu on the app's row and choose Disconnect.
- Choose Disconnect again to confirm.
The page says Disconnected. The application will have to be authorised again before it can act on your account. Every access the app held for your login is withdrawn, not just its current session.
Personal API tokens are not listed here. You manage those under Settings → Developer → API & MCP.
What gets recorded
Signing out a device, signing out all other devices and disconnecting an app each appear in your audit log under Security.
