I don’t know of a good reason not to use FaceID, and I can think of a bunch of good reasons to use it.

As I mentioned in a previous comment, your biometric data lives in the Secure Enclave on your phone—it never, ever leaves your phone. It’s not even visible to the operating system on your phone outside of the Secure Enclave. Apps that use FaceID for authentication, like banking apps, simply get a yes or no answer from the Secure Enclave; they have absolutely no access to the underlying biometric data.

Using FaceID allows you to use a longer, more complex passcode, since you don’t have to enter it very often. It also minimizes the odds that you’ll have to enter your passcode in a public place, where someone might see you enter it, grab your phone, and run off with it. Someone who has possession of your phone and knows your passcode can take your Apple account from you permanently, with no chance of your ever recovering it.

Speaking of which, iOS 17.3 introduced Stolen Device Protection to protect you from this. It’s a very good thing, and everyone should turn it on. It requires that you use FaceID on your phone.

On top of all this, FaceID just works really well. Just pick up your phone and start using it.
