Google's giving Android users an extra tool to keep their phones safe with the mandatory biometric security of Identity Check.
How much you want to bet that this is not going to be a feature in AOSP, but will only be on the Google versions of Android.
There's no reason why it can't be supported. ROMs like Graphene have been supporting longer passwords for ages so seems like some arbitrary Google restriction. Yet another reason why I stay degoogled.
I mean, the optical fingerprint sensors they've been using on the Pixels are absolutely garbage, so I will never use this feature.
I learned it from another poster. I did the brightness trick when when I setup my fingerprintes (you setup four finger prints with the same finger, but with each fingerprint setup you change the brightness by %25 step. you start with the lowest brightness [assume it's 0%] to the highest [%100] with each setup).
Thanks to that trick, I had at least %80 unlock success rate with my previous pixel 8P Pro!
I upgraded to the P9 Pro with the ultrasonic sensor, and unfortunately it's actually worse than the optical for me, and add to that brightness trick doesn't work with it either since it uses a different tech...
So it's 2FA for unlocking your device, which is good in principle but will need some serious reliability updates first
