Current Limitation

Currently, if an additional adapter is used, and login is attempted without additional data is thrown, error code -1 is thrown. Also, if there is a throw from within validateLogin, the error code is 141.

Feature / Enhancement Description

The error codes for each of these cases should be specific, so UI can update to allow users to provide additional auth data.

I assume this would be breaking; added the label.
