 Por último, el correo debe ser válido, ya que para activar el 2FA se enviará un mail de activación. Los grupos se pueden dejar como están, porque es para configuraciones más avanzadas.
+===== Integración con Nginx =====
+Para integrar Authelia con el proxy inverso Nginx, aplicaremos la siguiente configuración a nivel del //virtual host// que vamos a proteger con Authelia:
+<code>
+set $upstream_authelia http://authelia:9091/api/verify;
+## Virtual endpoint created by nginx to forward auth requests.
+location /authelia {
+    ## Essential Proxy Configuration
+    internal;
+    proxy_pass $upstream_authelia;
+    ## Headers
+    ## The headers starting with X-* are required.
+    proxy_set_header X-Original-URL $scheme://$http_host$request_uri;
+    proxy_set_header X-Original-Method $request_method;
+    proxy_set_header X-Forwarded-Method $request_method;
+    proxy_set_header X-Forwarded-Proto $scheme;
+    proxy_set_header X-Forwarded-Host $http_host;
+    proxy_set_header X-Forwarded-Uri $request_uri;
+    proxy_set_header X-Forwarded-For $remote_addr;
+    proxy_set_header Content-Length "";
+    proxy_set_header Connection "";
+    ## Basic Proxy Configuration
+    proxy_pass_request_body off;
+    proxy_next_upstream error timeout invalid_header http_500 http_502 http_503; # Timeout if the real server is dead
+    proxy_redirect http:// $scheme://;
+    proxy_http_version 1.1;
+    proxy_cache_bypass $cookie_session;
+    proxy_no_cache $cookie_session;
+    proxy_buffers 4 32k;
+    client_body_buffer_size 128k;
+    ## Advanced Proxy Configuration
+    send_timeout 5m;
+    proxy_read_timeout 240;
+    proxy_send_timeout 240;
+    proxy_connect_timeout 240;
+}
+## Send a subrequest to Authelia to verify if the user is authenticated and has permission to access the resource.
+auth_request /authelia;
+## Set the $target_url variable based on the original request.
+## Comment this line if you're using nginx without the http_set_misc module.
+set_escape_uri $target_url $scheme://$http_host$request_uri;
+## Uncomment this line if you're using NGINX without the http_set_misc module.
+# set $target_url $scheme://$http_host$request_uri;
+## Save the upstream response headers from Authelia to variables.
+auth_request_set $user $upstream_http_remote_user;
+auth_request_set $groups $upstream_http_remote_groups;
+auth_request_set $name $upstream_http_remote_name;
+auth_request_set $email $upstream_http_remote_email;
+## Inject the response headers from the variables into the request made to the backend.
+proxy_set_header Remote-User $user;
+proxy_set_header Remote-Groups $groups;
+proxy_set_header Remote-Name $name;
+proxy_set_header Remote-Email $email;
+## If the subreqest returns 200 pass to the backend, if the subrequest returns 401 redirect to the portal.
+error_page 401 =302 https://auth.example.com/?rd=$target_url;
+</code>
+Se da por hecho que:
+  * Authelia está accesible por el proceso de Nginx con el nombre de host ''authelia'' en el puerto 9091(la URL sería http://authelia:9091). Adaptar a nuestro caso particular.
+  * La URL a la que quieres acceder a través de Authelia es https://auth.example.com.  Adaptar a nuestro caso particular.
+==== Usando la imagen de docker nginx-proxy ====
+Si el servicio que queremos proteger con Authelia es https://app.midominio.com, tenemos que crear un fichero llamado como el dominio (''app.midominio.com'') en la carpeta ''/etc/nginx/vhost.d/'' del contenedor con el siguiente contenido:
+<code>
+## Start of configuration add by letsencrypt container
+location ^~ /.well-known/acme-challenge/ {
+    auth_basic off;
+    auth_request off;
+    allow all;
+    root /usr/share/nginx/html;
+    try_files $uri =404;
+    break;
+}
+## End of configuration add by letsencrypt container
+## Virtual endpoint created by nginx to forward auth requests.
+location /authelia {

+Donde:
+  * ''http://authelia:9091/'' es el contenedor con Authelia.
+  * ''https://portal.authelia.com/'' es el servicio al que redirigirá si hay error
