Keychain duplicate item error causing new Anonymous user on every login. No way to recover. #5906
Description
[REQUIRED] Step 1: Describe your environment
- Xcode version: 11.4.1
- Firebase SDK version: 6.17.0
- Firebase Component: Auth
- Component version: _____
- Installation method: Unity Package
[REQUIRED] Step 2: Describe the problem
Steps to reproduce:
This is inside a Unity app using the Unity FirebaseAuthentication package but it seems to be an underlying issue with the ios sdk.
- Launch app
- Authenticate as Anonymous User. Get a new user every time.
Keychain seems to get in a bad state and there is nothing in place to self-heal.
[Firebase/Auth][I-AUT000001] Error loading saved user when starting up: Error Domain=FIRAuthErrorDomain Code=17995 "An error occurred when accessing the keychain. The @c NSLocalizedFailureReasonErrorKey field in the @c NSError.userInfo dictionary will contain more information about the error encountered" UserInfo={FIRAuthErrorUserInfoNameKey=ERROR_KEYCHAIN_ERROR, NSLocalizedFailureReason=SecItemCopyMatching (0), NSLocalizedDescription=An error occurred when accessing the keychain. The @c NSLocalizedFailureReasonErrorKey field in the @c NSError.userInfo dictionary will contain more information about the error encountered}
Every time the app is launched, it throws this error and generates a new anonymous user.
We had three ios Devices get into this state across ios12 and 13. This happened after installing over existing builds.
We could not break another device so we are not sure the exact repro steps.
Other relevant logs on these devices:
