How to manage dynamic WIFI configuration on esp8266 or esp32

One most common need when you use IOT device with WIFI is the first connection attemp, It’s very tedious to hard code WIFI parameter, but a library allows you to connect your esp8266/esp32 to different Access Points (AP) without having to hard code and upload new code to your board. Additionally, you can also add custom parameters (variables) and manage multiple SSID connections with the WiFiManager library.
