I'm trying to implement Touch ID login, but when user fails more than maximum attempts, I receive this error "Error Domain=com.apple.LocalAuthentication Code=-8 "Biometry is locked out." UserInfo={NSLocalizedDescription=Biometry is locked out.}"

I want to know:

  • How much time, and where can i check it is locked touch id?
  • Is possible to force unlock without show the passcode?
  • If user fails all attempts with passcode, how much time is locked touch id, or how can I force unlock it?

Thanks!

Touch ID, once locked-out due to incorrect tries, will be locked until the user enters the passcode. So there is no set time. The only way to unlock will be the passcode from this point onwards and there is no way to force an unlock, for obvious reasons.
