Fingerprint fallback in IOS


#1

I’m using SDK 27’s Fingerprint library. If the user incorrectly enters touch id and chooses “Enter Password”, it just closes the modal and doesn’t bring up the device passcode input.

in the code, Expo.Fingerprint.authenticateAsync() returns this when the user chooses “Enter Password”

{
	"error": "user_fallback",
	"success": false,
}

i have the same problem as Expo Fingerprint fallback to passcode
according to that thread, this behaviour is a bug. The device passcode entry should appear when the user chooses “Enter Password” after a failed fingerprint try.

Was the solution for this already integrated in SDK 27? How do i bring up the device passcode input?

Ended up upgrading the SDK to 30 and that fixed the bug. The device passcode input now appears whenever the user chooses “Enter Password” after a failed fingerprint try
