How will the browser be able to tell that the user is already logged in on another system?

How are you storing who is logged in?

i am using a database table in which i insert login userID and one bit column to store isLogin Value in 0 and 1.

Then when User2 logs in, update the db for User1 to set IsLogin=0

you can do this by using cookies.

When a user access your website using a new browser (Device A), creates a random string (as Session Token A) and stores at the user's browser's cookies with the expire date set to 180 days.

Store the random string (session token A) together with the user id in database.

Condition 1:
If the user access your website using the same browser (Device A), the same session token (Session Token A) will be sent to the server to verify that it is the same user.

Condition 2:
If the user access your website using another device (Device B), new session token (Session Token B) will be created. Delete "Session Token A" from database, so when next time the user re-access the website on old device (Device A), "Session Token A" will not able to be verified as it is already not existed in database. Therefore, user will longer able to access your website from Device A.

That's not how it works. It's based on session timeout, and that can only be established when the user navigates in the browser.

You could do it via a database mechanism that utilizes jobs and/or triggers, but describing that mechanism here is fairly well beyond the scope of what QA is intended for.

Solution 2

You need to manage a database to manage all login session information. If user request for logout invalidate all the session associated with that account.

Still my suggestion would work. And also look for any solution offered by any solution by your framework to track all available session by current user
