Backend system authentication and token-based authorization play crucial roles in ensuring secure access to a software application. Authentication verifies the identity of a user, while authorization determines what actions they are allowed to perform. Token-based authorization involves the use of tokens, which are securely generated and exchanged between the client and server to grant access. These tokens are typically in the form of JSON Web Tokens (JWTs) and contain encoded information about the user and their permissions. They can be stored in client-side storage, such as cookies or local storage, and sent with each request to the backend for validation. By implementing backend system authentication and token-based authorization, developers can protect sensitive data and ensure that only authorized users can access and manipulate the system.
