Authentication Token
Explore how to implement authentication tokens in a Spring Boot backend. Learn to generate, store, and validate tokens linked to users, handle exceptions, and test the authentication flow to secure user sign-ups and logins.
After we log in, we’ll get a token from the API. This will be the authentication token and will be sent for every subsequent request.
On the backend, we’ll check the token, and retrieve the corresponding user. If the user is not valid, we’ll throw an exception.
