Connecting to trusted devices
If you have a device that you connect to regularly using Bluetooth® or NFC, for
example, a home entertainment system or a fitness tracker, you can add it as a
trusted device and bypass the added security of the lock screen to save time. This
feature is suitable if you're normally in a secure place when you use this device. In
some cases, you may still need to manually unlock your device before a trusted
device can be connected.
It is not recommended to add devices that are constantly connected to your device as trusted
devices, for example, Bluetooth® keyboards or mice.
As soon as a trusted device is switched off or moves out of range, your screen locks and you
need your PIN, pattern or password to unlock it.

Making sure you're secure when using trusted devices
Different Bluetooth® devices support different Bluetooth® standards and security
capabilities. There's a possibility that someone could keep your Xperia™ device
unlocked by imitating your Bluetooth® connection, even if your trusted device is no
longer nearby. Your device is not always able to determine whether your connection
is secure from someone trying to imitate it.
When your device can't determine whether you're using a secure connection, you'll
get a notification on your Xperia™ device and may need to manually unlock it before
the trusted device can keep it unlocked.
Bluetooth® connectivity range can vary depending on factors like the model of your device,
the connected Bluetooth® device, and your environment. Depending on these factors,
Bluetooth® connections can work over distances up to 100 metres.
