Manage signed in devices
See where you are signed in, and sign out a phone you no longer use.
Open My Account, then Devices. Connected Devices lists every phone and computer signed in to your account. The one you are using is marked This device.
To sign a device out, tap Revoke on it and confirm. Do this straight away if a phone is lost or stolen.
You can be signed in on up to five devices at once. If you see a message saying you are already signed in on five devices, revoke one here first.
