Ensuring your device is protected
Your device includes security options, strongly recommended in case of loss or theft.
When using a security option to protect your device, it is crucial to remember the details
provided at setup.
Screen lock
Set a secure screen lock on your device using a PIN, password, pattern, or to prevent
others from using your device without permission. Once the screen lock is set, it is not
possible to unlock the screen or erase the content via a Factory Data Reset without
providing the screen lock information.
If you add your contact information on the screen lock, for example your email, this
information can be used to get your device back if you lose it.
Google account
Add a Google account so that you can use the Find my device service. In some
situations, you may also need to identify yourself for security reasons using your Google
account.
Find my device
Use the Find my device service to remotely locate, lock, unlock, or erase the content on
a lost device. After you have signed in to your Google account, Find my device is turned
on by default.
SIM card lock
Lock your SIM cards with a PIN to protect your subscription against misuse. The PIN is
required every time you restart your device.
IMEI number
Keep a copy of the IMEI number. If your device is stolen, some network providers can
use this number to stop the device from accessing the network in your country or region.
Backup
Back up the content on your device in case your device is damaged, lost, or stolen. See
Backing Up and Restoring Content on page 38.
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 type
to only a PIN or password. This occurs when your network administrator specifies a
lockscreen type for all EAS accounts for enterprise security reasons. Contact the
