Change wifi credentials Wifi

I have a code that is already burned in the ESP8266, right now I have to change the wifi password, is there's any better way to do that without burning the code.

Yes there is. Use the WiFiManager library. It will automatically connect with the stored credentials, but if it fails, it turns on a hotspot you can connect to and input the new credentials
