+ + In this example, two applications have been deployed along with Authelia and a fake mailbox in order to confirm your secret registration to Authelia: + +

+ Please note that app1 is publicly available and app2 is protected by Authelia.
+
+ You can start by visiting app1 and then try to access app2. Since app2 is protected by Authelia, you will be redirected to Authelia's portal.
+
+ If it's the first time you login in this cluster, you'll need to choose your authentication method and follow Authelia's instructions.

+ Once done, you'll be able to authenticate with your selected second factor method. +
