The first time you open this feature, you are presented with a four-digit passcode that is assigned to your device. This passcode can be used from another device to issue SMS commands, in the event that your phone is lost or stolen. You can lock, locate, activate a "scream" alarm and wipe your phone's data from your Norton account online or by sending your phone a text with that code. For example, if your phone is lost you can find its location by sending "locate 1234" to your number from another device.
In addition to these features, you can use the "sneak peek" function
from Norton's website to help find your phone or catch a thief in the
act. If your device is locked using Norton security, it will
automatically take a photo every ten minutes.
