Every time I log in from a shared computer on Stack Overflow, I am not able to log out.
Even if I click log out, it takes me to the home page and when I click the login link it automatically logs me back in. I neither allow my browser to save passwords or nor to remember me.
I get this message each time
Welcome back user. Click here to refresh the page
Each time I have to clear all my cookies from my browser to log out from it. Why does this happen?
If you click Log out on the page that looks similar to this one:
You'll notice the text at the bottom:
If you're on a shared computer, remember to log out of your Open ID provider (Facebook, Google, Stack Exchange OpenID, etc.) as well.
Clicking Logout only logs you out from the Stack Exchange sites but NOT from the Stack Exchange OpenID provider. That behavior is similar to what you get when using Google or Facebook. You don't expect Stack Exchange to log you out from Gmail or from the facebook timeline you're watching.
To get to your Stack Exchange OpenID page isn't that obvious though.
Its direct url is https://openid.stackexchange.com/
To get to it from the UI follow these steps. First go to My Logins, for example in your Network profile:
Now click change password (trust me, you're not going to change your password). After clicking you'll be on your OpenID profile page:
Now you can click on the Logout tab which will bring you to the actual logout page of the Stack Exchange OpenID provider:
You can click the Log Out button here. That will log you out from the OpenID provider.
After clicking that button you'll notice that you have to re-enter all your credentials if you want to login again in any of the Stack Exchange sites.
You are logged into two separate things:
If you log out of #1 and then attempt to log in again using the same provider, it will instantly log you back into the same account beacuse you are still logged into #2.
To log out of #2, if you use the StackExchange OpenId provider, you have to visit this URL : https://openid.stackexchange.com/ Once there, you can log out of the provider.
In both cases, logout is a two step function (unlike most sites). You first click a "logout" link to get to the logout page. Then, on that page, you have to click a Logout buttton. This is poor usability (this tripped me up twice) and should be clearer.
More important is the login for #1 should have a "logout from the provider" link on it so that you can at that point logout of #2. I have seen some openid implementations start to do this. Every provider might have a different logout address.
When you are click log out option on Stack Overflow than show log out page and click logout than not proper logout your account in 'Mozilla firefox' but 'crome browser' not show this problem.
Mozilla
sign up log in careers 2.0
Again log in option click than permanently logout your a/c and not login a/c after page refresh.
