Originally created by @Melcos1970 on GitHub (May 8, 2017).
Original GitHub issue: https://github.com/tzapu/WiFiManager/issues/367

I have made a small change to WiFiManager.cpp and .h to get a mid-term solution to the problem with WPS.
It's not the best way, but now you can use WPS if you are going to ..
I have no idea how to add suggestions to github, but I want to post them here so can add them if you want to use them.
The solution is actually simple .. I just add a button extra that makes a WPS call.

Changed:
Const char HTTP_PORTAL_OPTIONS [] PROGMEM = "<form action = " / wifi \ "method = " get \ ">

The main problem with WPS that i found is that it does not retain its password on reset.
Did you get this issue?

No not with WiFiManager.. My problem is if the WPS fail to connect and the go back til normal state, that is why i make a reboot after using WPS.

I know this is old but can you post your code in code blocks please use three ticks open and close

Hey, I think I found a solution to the WPS problem! The problem is that the device doesnt wait for the WPS setup (which can take some time) to be completed. Therefore I simply put a while loop that checks if the setup was completed like so: (includes a timeout after 30s)

WiFi.mode(WIFI_STA);
bool wpsSuccess = WiFi.beginWPSConfig();
if(wpsSuccess) {
  String newSSID = WiFi.SSID();
  if(newSSID.length() > 0) {
    DEBUG_WM(F("WPS Success"));
    unsigned long start = millis();
    while (WiFi.status() != WL_CONNECTED && millis() - start < 30000) {
      yield();
    }
    if (WiFi.status() == WL_CONNECTED) {
      DEBUG_WM(F("WPS Connected"));
      connect = true;
      ESP.reset();
    } else {
      DEBUG_WM(F("WPS Failed"));
      connect = false;
    }
  } else {
    DEBUG_WM(F("WPS Failed"));
    connect = false;
  }
}

Just put this code instead of:

WiFi.mode (WIFI_STA);
delay (1000);
startWPS ();
delay (5000);
ESP.reset ();
delay (2000);

and it should work (at least on my machine)

Does anyone still use WPS, isnt it a vulnerability
