 In case of a private redirect, the app will be available to logged in users only. This could be useful if you want to protect behind the SSO an app from your local network or from the server (e.g., a Docker container or an app that does not have user management or password protection).
 
 **IMPORTANT:** Make sure that the app you want to protect CANNOT be accessed by its port or another direct link. Otherwise, your app will only be protected in YunoHost but would still be available through its direct link. In the case of a Docker container, the port of the container will have to be local (e.g., -p 127.0.0.1:9000:9000).
