Two-Factor Authentication <em>(as known as 2FA)</em> is a kind (subset) of <a href="https://en.wikipedia.org/wiki/Multi-factor_authentication" class="urlextern" title="https://en.wikipedia.org/wiki/Multi-factor_authentication" rel="nofollow">multi-factor authentication</a>. It is a method to confirm a user's claimed identity by using a combination of two different factors between:

|

<ol>
|
|
<li class="level1"><div class="li"> something they know <em>(login / password, …)</em></div>
|

|
<li class="level1"><div class="li"> something they have <em>(U2F Key, smartphone, …) </em> </div>
|
|
</li>
|

<li class="level1"><div class="li"> something they are <em>(biometrics like fingerprints, …)</em></div>
|

</li>
|

</ol>

Since 2.0, LLNG provides some second factor plugins that can be used to complete authentication module with 2FA :

If you don't want to use self-registration features for U2F, TOTP and so on, you can set tokens by yourself <em>(in your LDAP server for example)</em> and map it to <code>_2fDevices</code> attribute. <code>_2fDevices</code> is a JSON array that contains token descriptions :

|
|
<pre class="code json">[ {"type" : "TOTP", "name" : "MyTOTP", …}, {<other_token>}, …]</pre>

To develop a new 2FA plugin, read <code>Lemonldap::NG::Portal::Main::SecondFactor (3pm)</code> manpage. Your 2F module must be a Perl class named <code>Lemonldap::NG::Portal::2F::<em><custom_name></em></code>. To enable it, set <code>available2F</code> key in your <code>lemonldap-ng.ini</code> file :
|
|
</p>
|
|
<pre class="code ini"><span class="re0"><span class="br0">[</span>portal<span class="br0">]</span></span>
|
|
<span class="re1">available2F</span> <span class="sy0">=</span><span class="re2"> U2F,TOTP,<custom_name></span></pre>
|
|
|
|
<p>
|
|
To enable manager Second Factor Administration Module, set <code>enabledModules</code> key in your <code>lemonldap-ng.ini</code> file :
|
|
</p>
|
|
<pre class="code ini"><span class="re0"><span class="br0">[</span>portal<span class="br0">]</span></span>
|
|
<span class="re1">enabledModules</span> <span class="sy0">=</span><span class="re2"> conf, sessions, notifications, 2ndFA</span></pre>
