As such, when selling or transferring ownership of your device, make sure to disconnect your account and remove your SD card. You can delete all data on your SD card by navigating to Settings > Battery and device care > Storage > SD card > Format > Format SD card.

Information regarding FRP (Factory Reset Protection) Authentication after a Factory data reset

In accordance with Google’s security policy, this screen is displayed on devices with FRP (Factory Reset Protection) that was rolled out starting from Android 5.1 (Lollipop OS). This feature was enabled with the goal of preventing others from resetting and reusing lost phones and may require Google account authentication in such cases that the device was reset or rebooted via methods outside of normal rebooting or Factory data reset in Settings.

If you forgot your Google account password, it is recommended to visit a nearby service center and consult a technician for troubleshooting.
