Straight up I tried finger print unlock for less than a week before I cut the finger I used to unlock my phone so I had to change it.
Also a related unfun fact, you can be forced by the police to give biometrics but not information you know.‡ So having your devices lock via biometrics means that law enforcement can force you to unlock your devices.
‡ This applies to the US, I’m not sure if it applies elsewhere. IANAL YMMV
If you ever feel like you’re about to deal with a cop on your iPhone, mash the side button. 5x on the side button forces it into “ask for a passcode” mode. It’s emergency mode, but emergency mode forces you to out in a passcode to do anything other than show medical ID, turn off the phone (still trackable), or dial emergency services.
