Device security

Making sure your device is protected

Your device includes security options, strongly recommended in case of loss or
theft:
• Set a secure screen lock on your device using a PIN, password or pattern to prevent
anyone from accessing or resetting your device.
• Add a Google account to prevent others from using your device if it gets stolen or
wiped.
• Activate the Find my device web service. Using this service, you can remotely
locate, lock or clear a lost device.
Verifying the ownership of your device
Certain protection features require you to either unlock your screen with your PIN,
password, pattern, or enter your Google™ account information. Below are
examples of protection features and their required credentials:

For Find my device, it is necessary to enter information from a Google account. This can be
any Google account which you have set up on the device as an owner. If you cannot provide
the relevant account information during a setup process, you won't be able to use the
device at all.

Screen lock

Fingerprint functionality is not available in the US market.
There are several screen lock options available. The security level of each lock type
is listed below in order of weakest to strongest:
• Swipe: no protection, but you have quick access to the Home screen.
• Pattern: draw a simple pattern with your finger to unlock your device.
• PIN: enter a numeric PIN of at least four digits to unlock your device.
• Password: enter an alpha-numeric password to unlock your device.
• Fingerprint: place your registered finger on the power key to unlock your device.
It is very important that you remember your screen lock pattern, PIN or password.
If you forget this information, it may not be possible to restore important data such
as contacts and messages. If you have set up a Microsoft® Exchange ActiveSync®
(EAS) account on your Xperia™ device, the EAS security settings may limit the lock
screen type to only a PIN or password. This occurs when your network
administrator specifies a lock screen type for all EAS accounts for enterprise
security reasons. Contact the network administrator of your company or
organisation to check what network security policies are implemented for mobile
devices.
