How to manage Basic Authentication login with selenium c#?

Question

I'm making tests for the company where i'm doing my intership, but i don't know how to make that the script put my credentials in this part, if i enter in the page(myself, not the chromedriver) automatically gets the credentials from the login on my pc, obviously the test driver can't do that, that's why i get that alert, my question is how can i put the credentials there automatically? for now i'm putting a thread sleep and putting the credentials manually but i know that's not the optimal way to do it, i already try using the alert methods:

var alert = driver.SwitchTo().Alert();
alert.SetAuthenticationCredentials("user","password");
alert.Accept();

But I get this error:

Message: OpenQA.Selenium.NoAlertPresentException : no such alert
(Session info: chrome=87.0.4280.141)

And if i put a wait i got a timeout but nothing happen, as you can see i'm using chrome, i read a post from some years that chrome can't manage alerts, but i don't know if that's a thing today, i hope you guys can help me.

Answer 1

After days on research and trying, this is what works for me, i did a Google Chrome extension, the basic authentication method of http://user:password@mywebsite.com don't work anymore so i did this extension with my credentials, it's kinda risky but it was the only solution that i found

First you need to make a manifest.json:

{
  "name": "Webrequest API",
  "version": "1.0",
  "description": "Extension to handle Authentication window",
  "permissions": [
    "webRequest",
    "webRequestBlocking",
    "<all_urls>"
  ],
  "background": {
    "scripts": [
      "webrequest.js"
    ]
  },
  "manifest_version": 2
}

Then you need to create webrequest.js:

chrome.webRequest.onAuthRequired.addListener(function(details){
        console.log("chrome.webRequest.onAuthRequired event has fired");
        return {
                authCredentials: {username: "myusername", password: "mypassword"}
            };
    },
    {urls:["<all_urls>"]},
    ['blocking']);

After that you need to create the crx, in the chrome://Extension site in developer mode, after that you should login without problem in the website you're trying to login.
