Authentication with AxumMay 3, 2025Consider this scenario: you’re building a website that has a classic navbar at the top, this navbar has a button that reflects the user authentication status, showing a "Profile" button if the user is authenticated and showing a "Login" button in case the user is unauthenticated. I’d argue the simplest way to handle user authentication if you’re doing SSR is using cookies. To level up the cookie-based authentication we’ve discussed, authentication middleware offers a cleaner, reusable way to validate cookies and secure routes. With that in mind, let’s try and create our authentication middleware. /// /// This middleware performs JWT-based authentication by checking for `jwt` and `refresh` cookies.
