Don’t hard code WiFi Credentials with ESP8266, use WiFiManager

Posted on March 23, 2017 by robertwilkie

Nice tutorial for how to use WiFiManager to dynamically set wifi credentials for your ESP8266.  Of course I am a bit worried how “secure” this is. http://www.instructables.com/id/Avoid-Hard-Coding-WiFi-Credentials-on-Your-ESP8266/?ALLSTEPS
