It’s easy to disable Touch ID or Face ID!
Go to Settings> Touch ID & Passcode (on iPhone X is Face ID & Passcode). You will be prompted to enter your password. On the Touch ID & Passcode (or Face ID & Passcode on iPhone X), turn off all settings in the “Use Touch ID For” section, including “iPhone Unlock”, “Apple Pay” or “iTunes & App Store” .
Now, you’ll only be able to unlock your iPhone, use Apple Pay, or pay for purchases from iTunes and the App Store by entering your passcode. The biggest problem when turning off the Touch ID or Face ID is that you are more likely to use weak cryptography for convenience, because reports show that even a six-digit password is not strong enough. With Touch ID and Face ID, you can use strong passwords without the hassle of entering passwords too often. If they are off, be sure to use strong alphanumeric code.
