JSON Web Token (JWT) is a secure and compact authentication mechanism used to verify user identity and facilitate secure communication between client and server. JWTs are self-contained, meaning they contain all necessary information about the user, eliminating the need for server-side session storage. They are commonly used in API authentication, single sign-on (SSO), and securing web applications.
Ensures secure user authentication with digitally signed tokens.
JWTs are self-contained, reducing the need for server-side session storage.
Since authentication is stateless, JWTs improve speed and scalability.
Works across multiple platforms, including web, mobile, and cloud applications.
JWTs are widely used for user roles and access control management.
Allows seamless authentication across multiple applications with a single login.
JWT (JSON Web Token) is a compact, self-contained authentication token used for securely transmitting user information between parties.
JWTs are generated after successful user login and are sent with API requests for authentication and authorization.
JWTs use cryptographic signing methods (HMAC, RSA, or ECDSA) to ensure integrity and security. However, they should always be transmitted over HTTPS.
JWTs can be stored in HTTP-only cookies or localStorage, though cookies are preferred for better security.
Since JWTs are stateless, they cannot be revoked easily, but their validity can be managed using expiration times and blacklists.
