    Lol, we used to have "back to app" button, removed it.  we still
    have a cancel button on OTP page, this just restarts the flow.  IMO,
    if users want a "back to app" button, they should just add it
    themselves.<br>

                        &gt;<br>
                        &gt; There are possible security issues with
                        this that I don't know if we<br>
                        &gt; should do this or not.  Don't know if you
                        remember how ClientSessionCode<br>
                        &gt; works, it uses a hash of the client session
                        id and the action key<br>
                        &gt; currently stored in the.  When you switch
                        from authentication to<br>
                        &gt; required actions, the action key changes. 
                        Now, if you hit the back<br>
                        &gt; button on a required action page, it would
                        take you back to an<br>
                        &gt; authentication screen.  The code check
                        would fail because the action<br>
                        &gt; keys don't match.<br>
                        &gt;<br>
                        &gt; Do we actually need this action key stuff? 
                        Can we just let the flow<br>
                        &gt; manager put the browser in the correct
                        state?  So if an "authenticate"<br>
                        &gt; url is hit and the flow is on required
                        actions, just redirect to the<br>
                        &gt; required actions URL.   I just worry that
                        this is some sort of security<br>
                        &gt; hole somehow.  Maybe we're better off just
                        reseting and restarting the<br>
