Registered devices
Which machines can sign in as you, and what to do at the limit.
At the limit, a new device is refused rather than an old one dropped.
What it shows
Registered devices lists the devices signed in to your account, captioned with how many of the maximum are registered. The one you are using is marked This device. With none it says so.
At the limit the caption adds a warning: the limit is reached, so signing in on a new device will be refused until you remove one here.
That is the behaviour to understand before it happens. The platform does not quietly sign out your oldest device to make room — it refuses the new one. If you are locked out on a new laptop, this list is why, and the fix is to remove something from a device you still have.
Removing one
Remove asks you to confirm — sign this device out, and anyone using it will need to sign in again — and then asks for your authenticator code. Two steps, because removing a device is a security action.
The confirmation's wording is precise. Removing does not deregister a machine so much as sign it out; whoever has it can sign in again if they know your password and can pass two-factor.
When to look at this list
- After you replace a laptop or a phone — remove the old one.
- When a new device is refused — something has to go first.
- After a security alert, or if Last Login on your profile surprises you.
- When you have signed in somewhere you do not control, such as a shared staff machine.
The strongest action is not here: changing your password ends sessions more broadly, and is the right response when you think somebody else has your credentials rather than merely your laptop.
