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
•
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 lock screen type to only a PIN or password.
This occurs when your network administrator specifies a specific lock screen type for all EAS
accounts for enterprise security reasons. Contact the network administrator of your company
or organization to check what network security policies are implemented for mobile devices.
