I'm working on a site that uses basic authentication. Using Chrome I've logged in using the basic auth. I now want to remove the basic authentication details from the browser and try a different login.
How do you clear the current basic authentication details when using Chrome?
It seems chrome will always show you the login prompt if you include a username in the url e.g.
This is not a real full solution, see Mike's comment below.
You can open an incognito window Ctrl+Shift+n each time you are doing a test. The incognito window will not remember the username and password the last time you entered.
To use this trick, make sure to close all incognito windows. All incognito windows share the same cache. In other words, you cannot open multiple independent incognito windows. If you login in one of them and open another one, those two are related and you will see that the new window remembers the authentication information from the first window.
The authentication is cleared when you exit Chrome.
Note however, that by default Chrome is running apps in the background, so it may not really exit even if you close all Chrome windows. You can either change this behavior under advanced setting, or e.g. under Windows, you can completely exit Chrome by using the Chrome icon in the systray. There should be an icon if Chrome is still running, but maybe you'll find it only in the popup with the hidden icons. The context menu of the Chrome icon has an entry to completely exit Chrome, and you can also change the setting for running apps in the background using that menu.
SettingsShow advanced settings...System uncheck the box labeled: Continue running background apps when Google Chrome is closedfunction logout(url){
var str = url.replace("http://", "http://" + new Date().getTime() + "@");
var xmlhttp;
if (window.XMLHttpRequest) xmlhttp=new XMLHttpRequest();
else xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4) location.reload();
}
xmlhttp.open("GET",str,true);
xmlhttp.setRequestHeader("Authorization","Basic YXNkc2E6")
xmlhttp.send();
return false;
}
There is no way to do this in Chrome as yet (Chrome 58)
I have found the best solution is to open the url in an Incognito window, which will force you to re-enter the basic authentication credentials.
When you want to change the credentials, close the Incognito window and launch another Incognito window.
This isn't exactly what the question is asking for but in case you accidentally saved basic auth credentials and want to clear them or update them:

Steps 1-4 can be quickly navigated with this link: chrome://settings/passwords
This worked in Chrome Version 59.0.3071.115
javascript: (function() {
var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState == 4) {
location.reload()
}
};
xmlhttp.open("GET", location.origin, true);
xmlhttp.setRequestHeader("Authorization", "Basic aW52YWxpZDoK");
xmlhttp.send();
return false;
})()
May be old thread but thought of adding answer to help others.
I had the same issue with Advanced ReST Client App, I'm not able to clear basic authentication from Chrome neither from app. It simply stopped asking for credentials!
However, I managed to make it work by relaunching Chrome using About Google Chrome -> Relaunch.
Once Chrome is relaunched, when I accessed ReST service, it will ask for user name and password using basic authentication popup.
Hope this helps!
I am using Chrome Version 83 and this is how I did it. Before following the steps make sure the tab of the site, whose Auth Details you want to delete is closed.
First, go to Settings >> Privacy and security.
Then click on Site settings option
Then click on View permissions and data stored across sites option
Search for the site whose Auth info you want to delete. In this example, I am using Stack Overflow.
Now click on the site and then click the Clear data button. 
Now restart your browser and you will be asked for a fresh login. For restarting you can type chrome://restart in the address bar.
As mentioned by @SalCelli, chrome://restart works. However, this relaunches all the tabs.
Another method is to launch in incognito mode as suggested by CEGRD
However, if you could not like to restart & use incognito, on Chrome 86 (Mac), I found that the answer provided by @opsb & Mike only works with the below additional steps.
Enter the wrong username in the url without the resources
eg: if the url is http://mywebsite.com/resources/, it will not work if I enter http://[email protected]/resources/, but will work if I enter only http://[email protected]/
However, entering the valid credentials will not work, as in the background, chrome still send the wrong user as part of the url, even though the url appears right in the address bar When prompted for credentials you would need to Cancel, and click the address bar and reload the page from pressing enter. Now enter the correct password
A lot of great suggestions here, I'll give the one that I found the most efficient:
Just change your password in the site. The old authentication will became outdated and Chrome will request it again.
Since I had a terminal open, I did a simple script to change the password and in two keypresses it were incremented.
In Chrome, on the right-hand side of the URL bar when you are at a password protected URL, you should see a small key symbol. Click the symbol and it will take you directly to the Password Management area where you can remove the entry. That will ensure you receive future prompts or have an opportunity to enter a new password and save it.
If you do not see the key symbol, that same Password Management area can be accessed by going to Chrome -> Settings -> Passwords and forms -> Manage Passwords. Or more simply, this URL – chrome://settings/passwords.
For Chrome 66 I found the relevant option under:
Using a new Incognito window is probably easier, but for those times you forget and want to clear the saved password, this does the trick without having to restart Chrome (which also works)
Weirdest thing, but in my case, I was trying to access a page with basic auth and Chrome was sending invalid credentials without even prompting for it. After I logged out from my LastPass plugin, everything was back to normal. So I think LastPass is starting to support Basic Auth but it's not giving the option of what password to use, it looks like it's just sending a random password for a domain that matches (which is very problematic in my case).
Thought it might help someone.
This is a quick trick.
For example you already input basic auth to url https://example.com by user1:password1. To clear it just open new tab then:
Goto: https://any:[email protected] then your password will be removed.
any:any is any string.
