TODO : show a form to add a new TOTP password
<p>On this page you can configure a new Authenticator app. Please use the authenticator app to scan the QR code.</p>
<p>Note: if you have not an authenticator app yet, you might want to use
<a href="https://play.google.com/store/apps/details?id=org.fedorahosted.freeotp" rel="noopener" target="_blank">FreeOTP
Authenticator</a> for example.</p>
<img src="data:image/png;base64,{{ qr_code }}" style="width: 150px; margin: 0px 20px;"/>
<p>If you can't scan the QrCode, please use the following parameters instead:</p>
<ul>
<li><strong>Account name:</strong> {{ account_name }}</li>
<li><strong>Secret key:</strong> {{ secret_key }}</li>
</ul>
<p>Once you have scanned the QrCode, please generate a first QrCode and type it below:</p>
TODO : add form
