What is the best way to automatically log out a user when a different user logs in on the same browser?

Question

What is the best way to automatically log out a user when a different user logs in on the same browser?

Currently, I am encountering an issue where there are two separate dashboards for different types of users - one for admin and the other for a merchant. The problem arises when an admin logs in on one tab and then a merchant logs in on another tab in the same browser. Upon refreshing the admin page, I notice that the navbar meant for the merchant appears, while the rest of the page remains as the admin's dashboard content. This situation may be related to how I handle storing tokens in the localStorage.

I am seeking advice on how to properly log out the previously logged-in user if a new user logs in on the same browser session. Any suggestions or solutions would be greatly appreciated.

Answer №1

If Internet Explorer is not a concern, I recommend using the Broadcast Channel API in place of localStorage events

To start, initialize your broadcast channel and listen for events

const bc = new BroadcastChannel("your_channel_name")

bc.onmessage = (e) => {
  // Implement your business logic here
  // Access the data sent through the channel using e.data
}

When you are ready to trigger the event

bc.postMessage("your logout message");

If you find yourself needing to sign out from other tabs, consider utilizing local storage events to pass signals between multiple tabs.

Initiate a logout event on the previously active tabs:

localStorage.setItem('logout-event', 'logout' + Math.random());

Any other open tabs can listen for this event using the following code:

window.addEventListener('storage', function(event){
    if (event.key == 'logout-event') { 
        // Implement your code here
    }
});

Whenever a new tab is used to log in as a merchant, follow the above steps to ensure all other users are logged out.

If you're looking for a way to ensure that each tab or session has a unique token that is deleted when the tab is closed, consider using sessionStorage instead of localStorage
