iOS 11 Has a Feature To Temporarily Disable Touch ID (cultofmac.com)
A new feature baked into iOS 11 lets you quickly disable Touch ID, which could come in handy if you're ever in a situation where someone (a cop) might force you to unlock your device. Cult of Mac reports: To temporarily disable Touch ID, you simply press the power button quickly five times. This presents you with the "Emergency SOS" option, which you can swipe to call the emergency services. It also prevents your iPhone from being unlocked without the passcode. Until now, there were other ways to temporarily disable Touch ID, but they weren't quick and simply. You either had to restart your iPhone, let it sit idle for a few days until Touch ID was temporarily disabled by itself, or scan the wrong finger several times. The police, or any government agency, cannot force you to hand over your iPhone's passcode. However, they can force you to unlock your device with your fingerprint. That doesn't work if your fingerprint scanner has been disabled.
"Baked into" implies it's non-removable and non-optional. "Included with" implies it's optional. The terms are discrete and worth using.
You'll be held in contempt until you provide it.

The difference is that the cops are already going to physically take your hand , stick it in ink, and force it onto paper if they have arrested you. They're going to go through your possessions and if they find keys, can try them on locks they also find on you.
They can't make you say anything though. In fact, they will specifically advise you of your right NOT to talk.
This is one of the reasons why biometrics make terrible single-factor authentication. If not for yubikey or smartcard as 2fa, I wouldn't use finger print on my laptop. Biometrics are better replacements for usernames than passwords, imo, especially given the limited ability to change most of them, and the fact that anyone who is in physical possession of both you and the device doesn't need your cooperation.

"Integrated" would be a less colloquial term and clearer and more transparent to a diverse audience.
"unlocking your phone with a password is considered different from using a fingerprint according to the law/police."
A fingerprint is physical, like a key. The taking of fingerprints does not fall within the category of either communication or testimony so as to be protected by the Fifth Amendment privilege. United States v. Wade, supra.
A PIN is knowledge, and protected.
