When you sign in to a Google Account on your device, Factory Reset Protection is turned on. Factory Reset Protection (FRP) prevents other people from using your device if it is reset to factory settings without your permission. For example, if your device is lost or stolen and a factory data reset is performed, only someone with your Google Account username and password can use the device.
You will not be able to access the device after a factory data reset if you do not have your Google Account username and password. For more information, see Factory Data Reset.
Caution: You should remove your Google Account before shipping your device to any service provider for service and before resetting the device to factory settings.
