What is Google FRP?
When completely resetting a mobile phone with a Google account entered, this function can only be used by entering the Google account at the first booting stage.
This operation is based on Google FRP (Factory Reset Protection), which has been installed since Android 5.1 (Lollipop OS) launch devices in accordance with Google’s security policy.
This function is applied to prevent others from reusing a lost mobile phone after initializing it, and the function is activated on mobile phones used by registering a Google account.
Google’s security policy allows you to register a Google account during the initial setup process and use it after authentication when the phone is reset and rebooted using an abnormal method other than ‘reset entire device’ in the phone settings.
Starting with Android 9 OS version, it can also be unlocked using the lock screen (pattern, PIN, password).
If you have lost your Google account password, we recommend that you visit a nearby service center and have it inspected by an engineer.
