Factory Reset Protection (FRP) Feature
What is Device Protection, or Factory Reset Protection (FRP)?
Android devices provide built-in security features you can use to protect your device and
information, including screen locks and data encryption. Data protection, or Factory Reset
Protection (FRP), is a security feature on Android devices with Lollipop 5.1 or higher.
FRP is automatically activated when you set up Google Account on your device. Once FRP is
activated, it prevents use of a device after factory data reset, until you log-in using Google
username and password previously set up on the device.
How does FRP work?
When you perform a Factory Data Reset, all settings are returned to the factory default settings.
All data is erased including files and downloaded apps.
If you have a Google Account set up on the device, FRP is active. This means that after reset,
you'll be required to log-in to the Google Account using the username and password. If you have
multiple Google Accounts set up on the device, you can log-in using any of the accounts.
If an unauthorized person tries to reset the device by another method, the device would still
require log-in using the Google username and password. This means that if your device is lost or
stolen, another person would not be able to reset it and use it.
What do I need to know about FRP?
If you want to reset your device to factory defaults, make sure you know your Google Account
and password, because you'll need to log-in at the end of the reset.
If you want to reset your device to factory defaults, but don't remember your Google username
and/or password, you can do one of these:
Check your device’s Account settings for your account name and reset your password via the
device or at
It can take 24 hours for the password reset to sync with all devices registered to the account.
Remove the account before you reset device.
If you already reset your device, but don't remember your Google username and/or password,
the device can't be used. In that case, you can do one of these:
