  - Merge "Don't give user the exact exception description"
  - Don't give user the exact exception description

    The exact description of the exception especially if related to
    cryptography cannot be given to the user as it may be abused by the
    attacker.

    To fix that, we started to use @ExceptionHandler for all exceptions
    in the LoginController as well.
