Model Name: ROG Phone 3
Firmware Version: .99
Rooted or not: No
Frequency of Occurrence: 2-3 times a week

In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.
========================================
My phone would randomly request me to enter my passcode, no matter what app i use. What's weird is that i can actually just swipe back and it won't ask for the passcode anymore, meaning i don't see any outcome whether i enter the passcode or ignore the request. May I know if this is a built in feature (which doesn't seem to work well seeing that i can just bypass it by swiping back) or there is an app triggering this request?

Also am unable to screenshot the request as the system did not allow me it was restricted. Managed to get a screenshot using the assistive touch app. Will take a photo once it comes out again

Also forgot to mention that my unit is not a Tencent unit with a reflashed firmware or anything like that and was bought from an authorised Asus reseller

Do you have developers settings enabled, or any third-party application that might be causing this?
I also see that you are running old firmware. Please update to the latest version and let me know if the issue persists.

From what I understand is if you have any of the biometric authentication enabled on the phone it will ask you for your pin code every 72 hours.
