Forgot Huawei P smart 2019 pin (cell phone not sim)?

I've just bought a new cell phone and since I always use the fingerprint, I never enter the pin, my siblings have found out and I then changed it, now I have turned off the device and must enter the pin.

Unfortunately helps to a factory reset ☹

They did not change the pin, they tried it and thought they would not find it anyway, then already and then I changed it

Sorry I got it wrong
