What can device management do?

You can manage the devices you have used to log in under Account security

You can log in with a HUAWEI ID using a maximum of 20 devices simultaneously. When the number of devices exceeds 20, the device whose login time is the earliest will be deleted from the list.

You can check the login time and rename devices. You can also delete a device from the list and log out from the device, in which case the device will become untrusted.
