How to remove pin lock from android

[Android Central Question]

Hi
I had pattern lock on my phone. I decided to set fingerprint lock but for that the current lock should be pin lock. So I set pin lock and fingerprint is set. Now I forgot my pin password and I can only unlock using fingerprint. How I can reset, change my pin lock. Because in settings I need to provide previous pin lock to change which I have forgotten. Hellp
I am using huawei P9 lite mobile.

I guess you'll have to factory reset. Either that, or use hypnotic recall to retrieve the PIN from memory.
Tell us if you need advice about fully backing up your personal data before resetting.

Welcome to Android Central! You have to remember these things, especially since Android devices will typically ask for your backup PIN/password/pattern from time to time to increase security (especially when doing a cold boot). You've never noticed that before?
