Device security
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 on 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
Screen lock
on
page 11 .
•
Add a Google™ account to prevent others from using your device if it gets stolen and/or
wiped. For more information, see
Why do I need a Google™ account?
on page 8 .
•
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 erase a lost device.
For more information, see
Finding a lost device
on page 16 .
Verifying the ownership of your device
When your device is protected, you need to either unlock your screen with your PIN,
password, pattern, or enter your Google™ account information depending on the
protection features you are using. Below are examples of protection features and some
of the required credentials:
