Learn how to add HTTP authentication with username and password to your ESP32 and ESP8266 NodeMCU web server projects using Arduino IDE. You can only access your web server if you type the correct user and pass. If you logout, you can only access again if you enter the right credentials.
The method we’ll use can be applied to web servers built using the ESPAsyncWebServer library.
The ESP32/ESP8266 boards will be programmed using Arduino IDE. So make sure you have these boards installed:
- Installing ESP32 Board in Arduino IDE (Windows, Mac OS X, and Linux)
- Installing ESP8266 Board in Arduino IDE (Windows, Mac OS X, Linux)
Security Concerns
This project is meant to be used in your local network to protect from anyone just typing the ESP IP address and accessing the web server (like unauthorized family member or friend).
If your network is properly secured, running an HTTP server with basic authentication is enough for most applications. If someone has managed to hack your network, it doesn’t matter if you use HTTP or HTTPS. The hacker can bypass HTTPS and get your user/pass.
Project Overview
Let’s take a quick look at the features of the project we’ll build.
- In this tutorial you’ll learn how to password protect your web server;
- When you try to access the web server page on the ESP IP address, a window pops up asking for a username and password;
- To get access to the web server page, you need to enter the right username and password (defined in the ESP32/ESP8266 sketch);
- There’s a logout button on the web server. If you click the logout button, you’ll be redirected to a logout page. Then, close all web browser tabs to complete the logout process;
- You can only access the web server again if you login with the right credentials;
- If you try to access the web server from a different device (on the local network) you also need to login with the right credentials (even if you have a successful login on another device);
- The authentication is not encrypted.
Note: this project was tested on Google Chrome and Firefox web browsers and Android devices.
Installing Libraries – Async Web Server
To build the web server you need to install the following libraries:
- ESP32: install the ESPAsyncWebServer and the AsyncTCP libraries.
- ESP8266: install the ESPAsyncWebServer and the ESPAsyncTCP libraries.
These libraries aren’t available to install through the Arduino Library Manager, so you need to copy the library files to the Arduino Installation Libraries folder. Alternatively, in your Arduino IDE, you can go to Sketch > Include Library > Add .zip Library and select the libraries you’ve just downloaded.
Web Server Code with Authentication
Copy the following code to your Arduino IDE.

You just need to enter your network credentials (SSID and password) and the web server will work straight away. The code is compatible with both the ESP32 and ESP8266 boards.
As an example, we’re building a web server that controls GPIO 2. You can use the HTTP authentication with any web server built with the ESPAsyncWebServer library.
How the Code Works
We’ve already explained in great details how web servers like this work in previous tutorials (DHT Temperature Web Server or Relay Web Server), so we’ll just take a look at the relevant parts to add username and password authentication to the web server.
Network Credentials
As mentioned previously, you need to insert your network credentials in the following lines:
const char* ssid = "REPLACE_WITH_YOUR_SSID";
const char* password = "REPLACE_WITH_YOUR_PASSWORD";Setting Your Username and Password
In the following variables set the username and password for your web server. By default, the username is admin and the password is also admin. We definitely recommend to change them.
const char* http_username = "admin";
const char* http_password = "admin";Logout Button
In the index_html variable you should add some HTML text to add a logout button. In this example, it’s a simple logout button without styling to make things simpler.
<button onclick="logoutButton()">Logout</button>When clicked, the button calls the logoutButton() JavaScript function. This function makes an HTTP GET request to your ESP32/ESP8266 on the /logout URL. Then, in the ESP code, you should handle what happens after receiving this request.
function logoutButton() {
var xhr = new XMLHttpRequest();
xhr.open("GET", "logout", true);
xhr.send();One second after you click the logout button, you are redirected to the logout page on the /logged-out URL.
setTimeout(function(){ window.open("/logged-out","_self"); }, 1000);
}Handle Requests with Authentication
Every time you make a request to the ESP32 or ESP8266 to access the web server, it will check whether you’ve already entered the correct username and password to authenticate.
Basically, to add authentication to your web server, you just need to add the following lines after each request:
if(!request->authenticate(http_username, http_password))
return request->requestAuthentication();These lines continuously pop up the authentication window until you insert the right credentials.
You need to do this for all requests. This way, you ensure that you’ll only get responses if you are logged in.
For example, when you try to access the root URL (ESP IP address), you add the previous two lines before sending the page. If you enter the wrong credentials, the browser will keep asking for them.
server.on("/", HTTP_GET, [](AsyncWebServerRequest *request){
if(!request->authenticate(http_username, http_password))
return request->requestAuthentication();
request->send_P(200, "text/html", index_html, processor);
});Here’s another example for when the ESP receives a request on the /state URL.
server.on("/state", HTTP_GET, [] (AsyncWebServerRequest *request) {
if(!request->authenticate(http_username, http_password))
return request->requestAuthentication();
request->send(200, "text/plain", String(digitalRead(output)).c_str());
});Handle Logout Button
When you click the logout button, the ESP receives a request on the /logout URL. When that happens send the response code 401.
server.on("/logout", HTTP_GET, [](AsyncWebServerRequest *request){
request->send(401);
});The response code 401 is an unauthorized error HTTP response status code indicating that the request sent by the client could not be authenticated. So, it will have the same effect as a logout – it will ask for the username and password and won’t let you access the web server again until you login.
When you click the web server logout button, after one second, the ESP receives another request on the /logged-out URL. When that happens, send the HTML text to build the logout page (logout_html variable).
server.on("/logged-out", HTTP_GET, [](AsyncWebServerRequest *request){
request->send_P(200, "text/html", logout_html, processor);
});Demonstration
Upload the code to your ESP32 or ESP8266 board. Then, open the Serial Monitor and press the on-board RST/EN button to get is IP address.
Open a browser in your local network and type the ESP IP address.
The following page should load asking for the username and password. Enter the username and password and you should get access to the web server. If you haven’t modified the code, the username is admin and the password is admin.
After typing the right username and password, you should get access to the web server.
You can play with the web server and see that it actually controls the ESP32 or ESP8266 on-board LED.
In the web server page, there’s a logout button. If you click that button, you’ll be redirected to a logout page as shown below.
If you click the “return to homepage” link, you’ll be redirected to the main web server page.
If you’re using Google Chrome, you’ll need to enter the username and password to access the web server again.
If you’re using Firefox, you need to close all web browser tabs to completely logout. Otherwise, if you go back to the main web server page, you’ll still have access.
So, we advise that you close all web browser tabs after clicking the logout button.
You also need to enter the username and password if you try to get access using a different device on the local network, even though you have access on another device.
Wrapping Up

Again, nice tutorial. Works fine, but need more explanation on the controlling of GPIO 2.
I’m confused on how that part works. Since a NodeMCU is backwards with the LED, tried to make it look correct, but really got messed up.
Hi.
Replace the following line:
with
Replace this line:
with this one
I think this should do the trick.

The second line is the one I missed, however, now it stays off and outputs a 0 on serial. I’m missing something here.
You can teach me how to add buttons. on the web server please
good afternoon,
LOGOUT button (esp32) does not work
Hi Jose.
What do you mean? How does it behave?
Regards,
Sara
Boa tarde Sara.
Bom funciona tudo menos botão LOGOUT, não faz nada, parece que não gera o 401.
Fico muito grato pela pronta resposta.
Beiral
Olá.
Já modificamos o código e alteramos o tutorial.
Agora já deve funcionar.
Cumprimentos,
Sara
Hello,
Nice tutorial like always :p
Also possible to do or to add https instead of http?
Regards
At the moment I don’t have any examples on that subject, but please read the “Security Concerns” addressed at the beginning of this post.
You can find all our ESP32 projects here: https://randomnerdtutorials.com/projects-esp32/
Good Afternoon,
I have the same error with the Logout-Button (no reaction, no login window).
Kind Regards

OIII Sara
voltei a carregar o exemplo e funcionou diferente. agora ele sai da pagina porem se vc pedir para entrar ele não pede a autenticação
“Logged out or return to homepage.
Note: close all web browser tabs to complete the logout process.
ok, fico grato por informações
Beiral
hi Sara can you help me please. i upload the code no problem at all. but the serial monitor is always connecting to wifi. i cant find also the wifi credential can you help me how? thank in advance love your project.
Hi George.
You need to insert your network credentials, which is the name of your Wi-Fi network and the password to access it.
Usually, under the router there’s a label with the network credentials: SSID and password.
Regards,
Sara
I already put a wifi credentials but still connecting. I cant even find the wifi name on the esp32 on my phone. Thanks in advance
thanks sara…
Good Afternoon,
My solution:
server.on(“/logout”, HTTP_GET, [](AsyncWebServerRequest *request){
//request->send(401);
return request->requestAuthentication();
});
Would that be okay?
Kind Regards
Juergen B.
Hi.
We’ve modified the tutorial. It should be working now.

what is the command line to authenticate automatically the admin & password?
Hello Paulo. In the past, you could type in the browser URL bar: http://admin:[email protected]
However, that method no longer works.
Como posso adicionar outro user ao programa? Tentei assim e não consigo autenticar
const char* http_username = “admin”;
const char* http_password = “admin”;
const char* user1 = “arroz”;
const char* user1_password = “arroz”;
server.on(“/”, HTTP_GET, [](AsyncWebServerRequest *request)
{
Serial.println(request->authenticate(http_username, http_password));
if(!request->authenticate(user1, user1_password))
return request->requestAuthentication();
if(!request->authenticate(http_username, http_password) || !request->authenticate(user1, user1_password))
return request->requestAuthentication();
server.on(“/update”, HTTP_GET, [] (AsyncWebServerRequest *request) {
if(!request->authenticate(http_username, http_password) || !request->authenticate(user1, user1_password))
return request->requestAuthentication();
Boa Tarde !, Rui como seria o caso inverso disso ? , ex : consumir uma API web que precise autenticar . Ao invés de conexão com ESP32 o próprio se conectar em uma API web .
Hi Sara
Very good tutorial. I am fan of of random nerd tutorials. The tutorials are very
well explained. I request you to add a wi-fi manager so the wifi credentials
hard coding can be avoided.

Harnam
Can you also do this on micropython? Thank you.
Yes, but unfortunately I don’t have any tutorials on that exact subject. We’ll try to post something like that in the future.

Hi,
Thanks for great tutorials.
how can I add second button to control another device.
thanks for great Job.

Hello Junaid,
You can use the code in this project to use multiple buttons automatically (just define the number of outputs and GPIOs number): https://randomnerdtutorials.com/esp32-esp8266-relay-web-server/
Hi people, im daniel from colombia, its exciting, i made this application 3 months ago and i would like to know if it is possible to do it with an https server ?, i was following this tutorial youtube.com/watch?v=Wm1xKj4bKsY and i achieve to implement the https server. but i did not succeed in implementing the authentication, greetings to all and thank you very much in advance
Hi! Thanks for a cool tutorial. For anyone trying this. When using ASYNCTCP and webservers you can not add delay. Instead of that you should “manage” your relay buttons in the loop() function and make an constant state.
void loop() {
if(doorState == 1){
Serial.println(“opa”);
digitalWrite(5, 1);
delay(3000);
digitalWrite(5, 0);
doorState = 0;
Serial.println(“opa baiges”);
}
}
And instead of doing digitalWrite(pin, inputMassage.toInt())
you would do
doorState = inputMassage.toInt()
Then it would trigger the relay in the loop() function.
Hi!.. nice tutorial. can i add a program so that when i access the ESP 32/8266 web server i could change the username and password so the next time you access the Authentication you input the new username and password? Thanks in advance!.
Hi.
Yes, you can do that.
You need to create a page with an HTML form that updates the username and password variables and saves them in SPIFFS, for example.
You can take a look at this tutorial that might help: https://randomnerdtutorials.com/esp32-esp8266-input-data-html-form/
Regards,
Sara
Hi Sara!
Thanks for replying.. so i still need to program/create a button just like the “Log Out” button already in the program so that it can go the HTML form that updates the username and password? .. sorry, im a newbee.. hope you could share a sketch on how i can incorporate the two (authenticated web server and the html form to change username and password).. thanks again in advance.. 🙂
Olá mais uma ves um ótimo post meus parabéns , mas ao invés de criar uma pagina assincrona no espteria como puxar a pagina do spiffs.
Obrigado !
Olá.

ESP32/ESP8266 Web Server HTTP Authentication (Username and Password ProtectedHello,
I created a project on ESP8266 with your arduino sketch and it works fine and thank you for it. However, I believe the program does not quite match the photos. Indeed, we can see the return of the state of the relay, while on my order web page there is no state displayed. Could you please correct this flaw? Being a beginner in this field, I failed to get it. On the other hand I managed to add a second channel and it works well. I thank you in advance. Cordially. Jean Yves
Hi.
You are right.
I’m sorry about that.
I didn’t notice that those lines were missing.
The code is now updated and should work as expected.

can you show me how i have to change this line please ?
request->send_P(200, “text/html”, index_html, processor);
Hi.
You should specify the filesystem as follows:
server.on(“/”, HTTP_GET, [](AsyncWebServerRequest *request){
request->send(SPIFFS, “/index.html”, String(), false, processor);
});
You can follow this tutorial to learn how to serve HTML files saved on the data folder:

i have problems while changing the username and password on webpage.
can you please help me ?
when i define global values out of setup()
i can use them in this form :
server.on(“/”, HTTP_GET, [](AsyncWebServerRequest *request) {
if(!request->authenticate(hUsername, hPassword)){
return request->requestAuthentication();
}
Serial.println(“root /index.html should be here!!”);
});
but when my user decide to change those usernames and pass
the program returns wrong value : and then crashes
.
excuse me for my poor english .
Hi, is it able to have multiple usernames & passwords for the http authentication?
Yes, try this
if (!request->authenticate(http_username, http_password)){
if (!request->authenticate(http_username2, http_password2))
{
Serial.println("İkinci if");
return request->requestAuthentication();
}

I would like to use a wifi manager and have an authentication page
And use my esp 8266 in wifi repeater mode and have access to my esp8266 even if it is not connected to any network I do not want it to be able to restart if it has missed or c connected
Sara,
everything works great, but I couldn’t get more buttons…
Could you make it work with an option for more buttons?
Hi, in the projects “ESP32-CAM Car Robot” you use the library “esp_http_server.h” instead of “ESPAsyncWebServer.h”
How can i use Authentication with esp_http_server.h ?
Thank you so much.
I am wondering how all this could be done if I had all the files (index.html, style.css for the root webpage(index.html) and logout.html) in SPIFFS inside the folder “data”.
The line: Logout would be inside index.html file? and inside the script tags of this html file would be the definition of the logoutButton function? here in this function xhr is used, how that can be changed so as not having xhr but only SSE events inside my sketch?
we would have inside sketch something like that: (??)
// Route for root / web page
server.on(“/”, HTTP_GET, [](AsyncWebServerRequest *request) {
if(!request->authenticate(http_username, http_password))
return request->requestAuthentication();
request->send(SPIFFS, “/index.html”, “text/html”);
});
// Route to load style.css file
server.on(“/style.css”, HTTP_GET, [](AsyncWebServerRequest *request) {
request->send(SPIFFS, “/style.css”, “text/css”);
});
server.on(“/logout”, HTTP_GET, [](AsyncWebServerRequest *request){
request->send(401);
});
server.on(“/logged-out”, HTTP_GET, [](AsyncWebServerRequest *request){
request->send(SPIFFS, “logout.html”, “text/html”);
});
The line: button onclick=”logoutButton()” Logout /button would be inside index.html file?
Hi.
Yes, all files can be in the data folder instead of in the Arduino sketch.

Sara
Hello Sara,
With an ESP8266-01, I would like to carry out a circuit allowing the switching of an output (for example activating a relay) and an entry of detection of an event (for the opening of a door) with an authentication by words of pass. I failed to achieve this. However, I made and modified two of your sketches.
1- Sketche for the web server with password authentication that I modified in two outputs.
2- Sketche to warn via Telegram when a door is open, I changed it for two doors and it works perfectly.
With these two sketches, I wanted to transform them to have an output order (relay) and an entry (door detection) with password for the internet all via Telegram. But I can’t do it, and I have mistakes. I didn’t find this sketche on your presentation Internet page but maybe you have it somewhere? If not, do you think of such an achievement soon? With my thanks for your answer. Best regards. Jean Yves
Hello Sara,
I love your nice tutorials. They helped me a much getting started with ESPs.
I have the same problems logging out like others befor. It seems that it doesn’t work. I found out that you need to close the whole browser, closing only the website-tab from the tabbar is not enough.
Anyway, I browse a bit about logging out from a simple HTTP connection and it looks like I found a way to do.
xhr.open(“GET”, “/logout”, true, “log”, “out”);
I simply open the XMLHttpRequest() with a “dummy login” (User=”log”, Password=”out”). The connection is now authorized with this new dumm login.
If you then try to open the “/” page (also works in the same tab) the “request->authenticate(http_username, http_password))” returns “false” and you will be asked for the correct login.
Thanks a lot,
Dominik
CODE NOT WORKING
What exactly is not working?
Hi, what a wonderful tutorials those ones you make, thank you so mucho for all of them.
I need to ask you something about it: I’m working on an applicatio that in certain cases updates one page at a regular intervals and because of that every time the page is updated it ask me to load again the credentials but, the authentication emerging window doesn’t shows the checkbox to allow the browser to remember the user and password, just like the authentication window you showed. How can I make the browser to allow remember the user and password?. Thanks in advance for the help.
