Custom authenticator

How to create custom authenticator?

• PasscodeView supports custom authentication methods for authenticating the user using PIN or pattern.
• An application can provide their own PIN or pattern authentication algorithms and hook it into the PinView or PatternView.
• In another case, the application can create authenticator to send PIN/Pattern entered by the user to the server for the authentication.

Custom pin authentication:

• Implement PinAuthenticator to the custom authenticator class.
• Implement isValidPin() method with your custom authentication logic. This method will be run in the background thread.
• isValidPin() can provide three different outputs based on the authentication status.
  • PinAuthenticationState.NEED_MORE_DIGIT - If the PIN is incomplete. PinView will let the user enter another digit. For the dynamic PIN size, this method will let authenticator decide the correct PIN size.
  • PinAuthenticationState.SUCCESS - This indicates that the user authentication completed and the user is authenticated.
  • PinAuthenticationState.FAIL - This indicates that the user authentication completed. But the user is not authorized.

Sample:

• Check out inbuilt PasscodeViewPinAuthenticator for the reference impementation.

Custom pattern authentication:

• Implement PatternAuthenticator to the custom authenticator class.
• Implement isValidPattern() method with your custom authentication logic. This method will be run in the background thread.
• isValidPattern() will return boolean.
  • True indicates that the user is authenticated successfully.
  • False indicates that authentication process completed and the user is not authorized.
