Does fingerprint sensor work on rooted devices? (OEM Unlock option)

Hello everyone,
I'm a potential Huawei P10 Lite buyer and would love a little insight from someone already owning the device that has it rooted.
I see that unlocking the bootloader is possible and officially supported by Huawei (props to them for that!). You need to enable the "OEM Unlock" option in Developer Options menu which displays a pop saying "WARNING: Device protection features won't work on this phone while this setting is turned on."
What does that mean exactly? What device protection features are lost (besides from the obvious unlock of the bootloader)? Can you still use fingerprint and password options?

Thanks for the info, and what are the said security features that are disabled? Only the locked bootloader?

Thank you, I know about that security issue and I have my data encrypted.
I was asking if Huawei meant this and only this by "WARNING: Device protection features won't work on this phone while this setting is turned on" or there is something else that gets disabled.
Thank you.

Is there a way to enable fingerprint recognition after unlocking the bootloader?

I want to root my device and in order to do that, I need to unlock the bootloader. However, when I try to unlock the bootloader using Xiaomi's unlock tool (https://en.miui.com/unlock/) it says that the fingerprint recognition will be disabled. Will there be any way to re-enable this once I've rooted the device?
I unlocked the bootloader with adb/cmd and fingerprint works normal. No problems so far.
"Xiaomi unlock tool" is not for Android One devices

No, that's not true. It probably applies to other Xiaomi devices, but this line of devices is special. These come with Android One, which runs Google's pure OS rather than regular Xiaomi devices that run MIUI.
I'm going to unlock and root (hopefully) mine. You shouldn't face any problems with the fingerprint.

Camera2 api and Bootlloader Locked. Possible?

Hi everyone. I just want to ask if is possible to get Camera2 api feature in our Mi A2 (No lite version) with the bootloader locked and without Root. I had a Mi A1 Before and I remember that was possible to get that feature with a temp root and modifying the a file. Obviously I'm talking about keep the bootloader locked of course. I'm just asking cause I don't like the Warning Message related to Bootloader Unlock. I really appreciate if someone has the answer to my question. Thanks for the help.
You need bootloader unlocked. If you unlock the bootloader and enable gcam but then lock the bootloader again you will lose gcam support.

Did you update with bootloader unlocked ?
Because I am afraid of bricking the phone while updating to android 10 with bootloader unlocked and camera api2 enabled. Please help me! Should I locked the bootloader ?
In fact, I tried to lock with command "fastboot OEM lock" but it failed. I did not mod the device except enabling api2. I haven't unlocked critical bootloader.

I have unlocked bootloader but I did not critical unlocked as I only had to enabled camera api2 persistently ; which I did successfully on android pie few month ago. Now my problem is I am in dilemma whether to install android 10 OTA, like I used to previously with unlocked bootloader or shall I have to relock and format device before updating ?
I have neither installed any custom recover nor any other mod except enabling api2 using temporary patched boot

I've tried many ROMs, the only one that is working flawlessly is Resurrection Remix (i'm on 8.6.5).
It fully supports both MIUI Cam and GCam (i'm using the_dise 4.5) with good video and audio recording, astro photography and Slow Motion. They also support selecting second camera for shooting.
All the other custom roms based on aosp have the crappy audio recording issue.

Camera2API for Xiaomi MI A2

Is there any way to keep camera2API even after locking bootloader?

I don't think so. To lock bootloader you need to have untouched system, boot. Otherwise your device will be bricked. I don't see reasons for relocking bootloader (your data will be wiped!)
