<h2>Two-Factor Authentication</h2>
<p>When two-factor authentication is enabled, you will be prompted to enter a six digit code from an
authenticator app (usually on your phone) when you log into this control panel.</p>
<div class="panel panel-danger">
<div class="panel-heading">
Enabling two-factor authentication does not protect access to your email
</div>
<div class="panel-body">
Enabling two-factor authentication on this page only limits access to this control panel. Remember that most websites allow you to
reset your password by checking your email, so anyone with access to your email can typically take over
your other accounts. Additionally, if your email address or any alias that forwards to your email
address is a typical domain control validation address (e.g admin@, administrator@, postmaster@, hostmaster@,
webmaster@, abuse@), extra care should be taken to protect the account. <strong>Always use a strong password,
and ensure every administrator account for this control panel does the same.</strong>
