What is Vivo Y100t FRP?
FRP, or Factory Reset Protection, is a security feature integrated into Android devices. It is also included on the Vivo Y100t by Google to prevent unauthorized access to the Vivo Y100t device. When FRP is activated on a smartphone, it links the Vivo Y100t device to the user’s Google account.
That makes it mandatory to verify the account credentials after performing a hard reset. In other words, FRP acts as a protective barrier. It ensures only the rightful owner can access the Vivo Y100t device.
Purpose of Vivo Y100t FRP
The primary purpose of Vivo Y100t FRP is to safeguard personal data and sensitive information stored on the Vivo Y100t device.
