Arduino WiFi/ESP8266 WiFi Password Changed I am working on a project for a friend who is not very tech savvy involving an ESP8266. It will need to be connected to his WiFi network. 

The issue is that he occasionally changed the password to his WiFi network. Since I will not be able to access this device at a moments notice, it needs to be able to adapt to a change in the password. Is this possible with the ESP8266, or should I switch to an Arduino WiFi board, or is something more powerful necessary?
The WiFiManager library was written for exactly this purpose.
