* In order to safely use challenge/response (async) mode, you must
27
* - implement a site-specific transform of the challenge, and/or
28
* - only allow async mode from secure locations.
30
* Note that you cannot easily just disallow async mode completely
31
* as you typically must provide a way to resynchronize the token.
