 Thanks to this [ESPAsync_WiFiManager library](https://github.com/khoih-prog/ESPAsync_WiFiManager) is based on and sync'ed with [`ESP_WiFiManager`](https://github.com/khoih-prog/ESP_WiFiManager), all the features currently supported by [`ESP_WiFiManager`](https://github.com/khoih-prog/ESP_WiFiManager) will be available. Please have a look at [`ESP_WiFiManager`](https://github.com/khoih-prog/ESP_WiFiManager) for those too-many-to-list features.

 ```cpp
-/****************************************************************************************************************************
-  This example will open a Config Portal when there is no stored WiFi Credentials or when a DRD is detected.
-  
-  You can reconfigure to use another pin, such as the convenience FLASH / BOOT button @ PIN_D0;.
-   
-  A password is required to connect to the Config Portal so that only who know the password can access the Config Portal.
-  
-  The Credentials, being input via Config Portal, will then be saved into LittleFS / SPIFFS file, and be used to connect to 
-  Adafruit MQTT Server at "io.adafruit.com" and publish a Temperature Topic
-  
-  Based on original sketch posted by "Marko"(https://github.com/wackoo-arduino) on https://forum.arduino.cc/index.php?topic=692108
