Feeding WIFI SSID, Passwords and Blynk key's via a webpage in the ESP8266 EEPROM

I made use of https://github.com/tzapu/WiFiManager to do the same. Code is here:

//#define BLYNK_PRINT Serial    // Comment this out to disable prints and save space
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <DNSServer.h>
#include <ESP8266WebServer.h>
#include <WiFiManager.h>         //https://github.com/tzapu/WiFiManager
#include <EEPROM.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "AUTHTOKEN";

void setup()
{
  EEPROM.begin(512);
  Serial.begin(115200);
  WiFiManager wifiManager;
  //wifiManager.resetSettings();    //Uncomment this to wipe WiFi settings from EEPROM on boot.  Comment out and recompile/upload after 1 boot cycle.
  wifiManager.autoConnect("NodeMCU");
  //if you get here you have connected to the WiFi
  Serial.println("connected...yeey :)");
  pinMode(BUILTIN_LED, OUTPUT);     // Initialize the BUILTIN_LED pin as an output, I like blinkies.
  Blynk.begin(auth, WiFi.SSID().c_str(), WiFi.psk().c_str());
}

void loop()
{
  Blynk.run();  // Commented out for a short time.
}
