<h5 id="a-proof-of-concept-for-bi-directional-two-factor-authentication-">A proof of concept for bi-directional two factor authentication.</h5>
<p><em>The intent of this design is to mitigate the real time phishing of two-factor authentication tokens, but more generally provide assurance that you are talking to the server you spoke to on registration.</em></p>
<p>It's called <strong>Veerless</strong>, as it doesn't let you veer off course from the genuine server.</p>
<h3 id="how-to-try-it-out">How to try it out</h3>
<ol>
<li>Download the code from <a href="https://github.com/joekir/veerless">https://github.com/joekir/veerless</a> follow the setup steps below.</li>
<li>Review the code in the chrome-extension, and if you agree its non-harmful then install that. (<a href="https://developer.chrome.com/extensions/getstarted#unpacked">help on how to do that</a>)</li>
<li>Navigate to <a href="https://veerless.josephkirwin.com/register">https://veerless.josephkirwin.com/register</a>. This endpoint will give you the <code>t0</code> and <code>server_secret</code> to add to your chrome extension, via the "options" page in the extension's settings.</li>
<li><p>Now you can login at <a href="https://veerless.josephkirwin.com/login">https://veerless.josephkirwin.com/login</a> with the user that you chose. The extension will be looking for:</p>
<ul>
<li>X-Veerless-Init header from the server to begin the login transaction</li>
<li>X-Veerless-Response header from the server containing its TOTP variant, that it will verify. </li>
</ul>
<p>If it can successfully verify the header, you shouldn't see any difference to a common 2FA login experience, except that you client TOTP will be provided in a notification. If it cannot successfully verify the header, it will cancel the request, and notify you of this.</p>
</li>
</ol>
<h3 id="more-fiddling">More Fiddling</h3>
<p>You could then try and setup your own local site, attempting to spoof the live demo ; )</p>
<ul>
<li>Using the code you downloaded in step 1. With the setup steps below</li>
<li>Create a line in /etc/hosts like this (which kindof simulates a dns hijack for you)<br><code>127.0.0.1 veerless.josephkirwin.com veerless</code> </li>
<li>Now try authenticate in the same way as step 4. Notice the extension should now detect that this is a spoofed site.</li>
</ul>
<h3 id="site-layout">Site Layout</h3>
<ul>
<li><a href="https://veerless.josephkirwin.com">/</a> - this README page.</li>
<li><a href="https://veerless.josephkirwin.com/login">/login</a> - used to complete the login flow with veerless chrome-extension assisting.</li>
<li><a href="https://veerless.josephkirwin.com/register">/register</a> - retrieves the initial time seed (<code>t0</code>) for TOTP and the server secret for a given user.</li>
