Ask about touch id.

Hello, everyone. I want to do fingerpriint recognition

on a limited number of occasions and login with a custom password instead of passcode.

If you have a guide for touch id, please let me know.

The sample code is also good

(For example, typing a password for an Apple ID if the AppStore fails to recognize a fingerprint.)

What platform are you working on? I’ve presumed that you’re on iOS, but it’s hard to say because all the terms you mention are also present on macOS.

A good place to start with Touch ID is the KeychainTouchID samplem code. To offer you more specific guidance I’d need to get a better handle on your requirements. Reading through your post it seems like you’re trying to override the system Touch ID user interface, which isn’t something we support.

I want to work on iPhone, iPad. It wants to use the way Apple provides, but it wants to do a little customization. The language used is object-c. The method is supported by appStore or the ID and password are to be customized. I hope keychainTouchID is helpful to me.

I would appreciate it if you could let me know if there is another way.

Ask about touch id.
