Question 1

How to add fingerprint authentication with react-native-code-verification?

Accepted Answer

Use the onPressTouchId callback to trigger your own biometric implementation, such as with react-native-biometrics or react-native-touch-id libraries, since the component doesn't include native biometric logic.

Question 2

Can I change the number of digits in the pincode input?

Accepted Answer

The README doesn't mention this feature, so it likely supports a fixed digit count (common for pincodes), meaning you'd need to modify the source code or find an alternative component for variable lengths.

Question 3

react-native-code-verification vs react-native-pincode-input: which should I use?

Accepted Answer

Choose react-native-code-verification for simple, color-customizable UIs with minimal setup, but opt for react-native-pincode-input if you need features like auto-focus, validation, or more styling options out of the box.

Question 4

How to handle invalid pincodes or show error messages?

Accepted Answer

The component lacks built-in error handling; implement validation in the onEnteredPincode callback and manage error states externally, such as by resetting the input or displaying alerts.

Question 5

Is it compatible with Expo managed workflow?

Accepted Answer

It should work if no native linking is required, but since it's a third-party React Native module, check for any dependencies that might necessitate ejecting from Expo for full functionality.

Question 6

How to customize the pincode screen layout, like adding a logo?

Accepted Answer

Limited to color props only; for layout changes, you may need to wrap the component in a custom view or fork the library, as it doesn't support additional UI elements directly.
