Making Sure Your Device is Protected
Your device includes several security options, strongly recommended in case of loss or
theft.
These options are as follows:
• 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.
Verifying the Ownership of Your Device
Certain protection features require you to either unlock your screen with your PIN,
password, or pattern, or enter your Google™ account information. Below are
examples of protection features and some of the required credentials:
Factory
Data
Reset
protection
Android™
Device
Manager
You must unlock your screen before you are allowed to perform a Factory
Data Reset.
If you remotely reset your device using this service, you must enter
the username and password for a Google™ account. The device
must be connected to the internet before the setup process can be
completed. Otherwise, you will not be able to use your device after
the reset.
For Android™ Device Manager, 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
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 Homescreen.
• 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.
It is very important that you remember your screen unlock 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 lockscreen
