WiFiManager/docs/GETTING_STARTED.md

Getting started

WiFiManager owns station credential recovery and a temporary configuration portal. Keep one instance for the life of the application.

#include <Arduino.h>
#include <WiFiManager.h>

WiFiManager wifi;

void setup() {
    Serial.begin(115200);
    wifi.setConfigPortalTimeout(180);
    if (!wifi.autoConnect("Example Setup", "change-me")) {
        ESP.restart();
    }
}

void loop() {
    // Normal work begins after autoConnect succeeds.
}

autoConnect() first tries stored station credentials. If that cannot connect, it starts the AP and portal with the supplied name and password. Use a Wi-Fi-valid AP password.

PlatformIO dependency

lib_deps =
    WiFiManager=https://github.com/alexhopeoconnor/WiFiManager.git#v3.2.0

The package includes the asynchronous web and TCP dependencies required by the selected ESP8266 or ESP32 target. Add WiFiManager as the application’s direct dependency; do not copy its internal dependency list into your project.

Next: build Basic Portal, then explore portal UI or portal API.
