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.
To add or remove a trusted Bluetooth® device
1 Make sure your device is paired and connected to the Bluetooth® device that
you want to add as a trusted device.
2 From your Home screen, tap
3 Find and tap Settings > Lock screen & security > Smart Lock.
4 In the Smart lock menu tap Trusted devices > ADD TRUSTED DEVICE >
Bluetooth.
5 Tap a device name to select it from the list of connected and paired devices,
then tap YES, ADD.
6 To remove a paired device, select it from the list and tap REMOVE TRUSTED
DEVICE.
To add or remove a trusted NFC device
1 Make sure your device is paired and connected to the Bluetooth® device that
you want to add as a trusted device.
2 Find and tap Settings > Lock screen & security > Smart Lock.
3 Tap Trusted devices > ADD TRUSTED DEVICE > NFC.
4 Follow the on-screen instructions.
5 To remove a paired device, select it from the list and tap REMOVE TRUSTED
DEVICE
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.
