Making sure your device is protected
You can prevent other people from using your device without your permission. For
example, if your device is lost, stolen, or wiped, only someone with your Google™
account or screen lock information can use the device. To make sure that your device
is protected, it is important that you set a secure screen lock and add your Google™
account to your device. It is crucial that you remember both your screen lock
information and your Google™ account credentials. To make sure your device is
protected, you can:
•
Set a secure screen lock on your device, that is, a PIN, password, or pattern screen
lock to prevent anyone from resetting your device. For more information, see
lock on page 12.
•
Add a Google™ account to prevent others from using your device if it gets stolen
and/or wiped. For more information, see
page 10.
•
Activate either the "Protection by my Xperia" or the Android™ Device Manager web
service. Using one of these services, you can remotely locate, lock or format a lost
device. For more information, see

password, pattern, or enter your Google™ account information. Below are examples
of protection features and some of the required credentials:

Screen lock
There are several ways to lock the screen. 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
