+			<p>Before you connect your account with an authenticator app, you will be asked to
+				enter your recovery key. If you do not have a valid recovery key, you need to
+				order a new one before you can connect your account with an authenticator.</p>
+			<p>Why?<br>The recovery key is the only way to unlink the authenticator app from
+				your Tibia account in various cases, among others, if:</p>
+			<ul style="list-style-type:square">
+				<li>you lose your device (mobile phone, tablet, etc.) with the authenticator
+					app
+				</li>
+				<li>the device with the authenticator app does not work anymore</li>
+				<li>the device with the authenticator app gets stolen</li>
+				<li>you delete the authenticator app from your device and reinstall it</li>
+				<li>your device is reset for some reason</li>
+			</ul>
+			<p></p>
+			<p>Please note that the authenticator app data is not saved on your device's account
+				(e.g. Google or iTunes sync) even if you have app data backup&amp;synchronisation
+				activated in the settings of your device!</p>
+			<p>In all these scenarios, the recovery key is the only way to get access to your
+				Tibia account. Note that not even customer support will be able to help you in
+				these cases if you do not have a valid recovery key.<br>For this reason, make
+				sure to store your recovery key always in a safe place!</p><br>Do you have a
+			valid recovery key and would like to request the email with the confirmation key to
+			start connecting your Tibia account to an authenticator app?<br><br><b>Enter your
+				recovery key:</b><br>
