Microsoft Defender can help you protect all of your devices--Windows, Mac, Android, and iOS--and can help you see the security status of all of those devices on a single, easy, dashboard.
Tip: If you have a Microsoft 365 Family subscription, and you're a Family Organizer in that subscription. you can also see the security status of your family's devices, if they share it with you. See Protect the whole family in Microsoft Defender.
To add more devices to your dashboard see Adding devices to Microsoft Defender.
Each person in your Microsoft 365 subscription can have up to 5 devices signed into Defender at a time.
To see your other devices
On your Defender dashboard, select View all on the lower part of the device protection card.
The Other devices list
Here you'll find a list of your other devices that are signed into Microsoft Defender, and possibly the devices of family members who have chosen to share their security status with you.
You can see if there are any pending alerts on those devices and the last time their security status was updated.
Important: If any of the devices on the list show an alert, or that a key protection is turned off, you'll need to sign in on that affected device - or contact the user of that device, if it belongs to a family member - to take action on those alerts.
Any device that hasn't been signed into in the last 90 days will automatically be removed from this list. For more information on manually removing devices from the list see Removing devices from your Microsoft Defender dashboard.
