JSON Web Tokens (JWTs) have gained widespread adoption as the dominant standard for managing authentication requests due to their improved security over single strings and stateless quality. A JWT consists of three parts: a header with declarations such as "alg" and "typ", a payload containing claims about the user and token, and a verified signature created using a secret key or public/private key pair. JWTs have evolved since their initial draft in 2010 and are now widely used in industries and enterprise systems like Netflix, CockroachDB, MongoDB, VMWare, and many others. In authentik, JWTs are used to manage user access with advantages such as cross-services efficiency, automated login, and expiration time setting, making them a highly effective method for enterprises.
