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 12.

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 11.

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 19 .

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:

Factory Data

Reset protection

You must unlock your screen before you are allowed to perform a Factory Data Reset.

Protection by

my Xperia

If you remotely reset your device using this service, you must enter the username and

password for a Google™ account associated with the service. 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.

Android™

Device Manager

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.

Software repair

If you use the Xperia™ Companion software to perform a software repair, you’re asked

to enter your Google™ account username and password when you start the device

after the repair is complete.

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. If you cannot provide

the relevant account information during a setup process, you won't be able to use the device

at all.
