ESP8266 Community Forum

I'm developing on the Adafruit Feather HUZZAH ESP8266 with the Arduino IDE. I ran some WiFi client examples with hardcoded SSID and Password and it seems that they have been stored in flash somewhere. How can I format the flash so I can blow away the stored SSID/PW? I tried using the FS.h library and the SPIFFS.format() function but I think the WiFi creds are stored somewhere else. Any tools out there for formatting?
