JSON Web Tokens (JWT)

JSON Web Tokens (JWT) are a secure way to verify identities online. Think of them as digital ID cards: when you log into a website, the server creates a token containing your information and a secret signature. This token is sent to you and stored, often in your browser. When you make subsequent requests, you include the token, allowing the server to quickly verify your identity without needing to check your password again. JWTs enable safe, efficient, and stateless authentication, making interactions smoother and more secure between users and online services.
