ESP8266 Captive Portal

Introduction

This Captive Portal Provides Multiple Languages, a Dashboard to view and change all settings in one place, password validation, a function to send validatet credentials to a webhook(for example: discord webhook or webhook.site) and a deauthing function(only in the Dual ESP version). This project is a proof of concept for testing and educational purposes. Use it only against networks and devices that you have permission to! If you have any questions or suggestions just create an issue or DM me on Discord under the username: heinzguenter.

Currently Supportet languages: English and German.

Credits: Spacehuhn for inspiration on the Design of the dashboard, adamff-dev for the idea and inspiration for the design of the captive portal pages, sankethj for inspiration for parts of the code and justcallmekoko without theire projects this would probably not exist.

Versions

The Captive Portal comes in two versions, one for a single ESP8266 and one for dual ESP8266's. The main difference is that the singe version doesnt have a deauther(because while deauthing the Captive Portal goes unressponsive and is there for useles) and the password validation feature is a bit worse. To use the dual ESP8266 version wire them according to the schematics(The led and the button are optional) and upload the master script to your master ESP8266 and the slave script to your slave ESP8266.
