In this video we will discuss how to use bearer token for authentication and retrieving data from the server.

We want to implement a page that retrieves employee data from the server. If the user is not authenticated, he should be automatically redirected to the login page. The user should be able to get to the data page, only if he is logged in.

At the moment, the only way to log off the user is by closing the browser window. As we are storing the bearer token in browser session storage, when we close the browser we loose it from the session. In our next video we will discuss, how to explicitly log out the user without closing the browser window.

The word "thank you" is very little compared to what you offer to all of us.Can anyone please tell in which table is stored the Bearer token in the server side, and is able to authenticate the client ?Thank you very much in advance.

Hello, My understanding on Web API is that its stateless http protocol. But here we do use sessionStorage to use / identify sessions. Is it violating RESTFUL service principles ? Can you please clarify ? If my question is irrelevant please ignore.

Hi, How do refresh my token on every request. For Instance. In my API i have set expired token as 5 mins for an example, even though I'm using my web page continuously without being idle my token will be expired after 5 mins.How do we resolve this, meaning how do i refresh token on every request or is there any way to handle this?
