There are different options you can configure for the cookie server side, like expiration times or encryption. The browser will then add the cookie upon receiving the response. To set a cookie, you just have to add it to the response the server sends back after requests. So authentication can be done automatically like that. Each time you make a request to a website, your browser will include the cookies in the request, and the host server will check the cookies. For authentication, the key could be something like 'username' and the value would be the username. Be sure to clear the cookies upon logout!Ī cookie is basically just an item in a dictionary. they need to be logged in), the server obtains the access token from the cookie and checks it against the one in the database associated with that user. Every time the client makes a request for a page that requires authorization (i.e. Henceforth, the cookies will be attached to every request (and response) made between the client and server.īack on the client side, we are now logged in. Be sure to set an expiration date/time to limit the user's session Attach it to a response cookie to be returned to the client.Store it in the database associated with that user.Still in the server, we do two things with the access token: If everything checks out, we're going to create an access token, which uniquely identifies the user's session. If it doesn't check out, we may deny them access by sending a 401 status code and ending the request. The server looks up the username in the database, hashes the supplied login password, and compares it to the previously hashed password in the database. He/she provides their username/password and again, this is posted as a HTTP request to the server. This way, if someone gains access to your database they won't see your users' actual passwords. The server receives this request and hashes the password before storing the username and password in your database. The client posts a HTTP request to the server containing his/her username and password. What does the browser need to do? What does the server need to do? In what order? How do we keep things secure?īefore anything else, the user has to sign up. To expand on Conor's answer and add a little bit more to the discussion.Ĭan someone give me a step by step description of how cookie based authentication works? I've never done anything involving either authentication or cookies. ![]()
