Description: Token exchange is a fundamental process in the realm of authentication and authorization in computer systems. It involves the action of replacing one access token with another, allowing users to gain permissions or access specific resources without needing to re-enter their credentials. This mechanism is particularly relevant in various architectures and web applications, where security and efficiency are paramount. Tokens are strings of characters that represent the user’s identity and permissions, and their exchange often occurs through APIs. This process not only enhances user experience by reducing the need for constant authentication but also strengthens security by limiting the exposure of credentials. Additionally, token exchange can include the renewal of expired tokens, allowing for secure maintenance of active sessions. In summary, token exchange is a key technique that facilitates identity and access management in digital environments, optimizing both security and usability of applications.
