JSON Web Tokens 🔐

JWTs (JSON Web Tokens) use cryptographic algorithm signatures to ensure data integrity. This helps authenticate the client and protect against malicious attacks.

🔒 Stateless Authentication
JWTs are stateless, meaning they contain all the user information needed for authentication directly within the token itself. This makes them highly scalable because they don't rely on the server to maintain a session store. Once the client is validated, there are fewer server calls since the token can be authenticated across multiple domains or services.

📊 JWTs vs Session-Based Authentication
Session-based authentication can be beneficial to legacy projects that aren't ready to implement token-based authentication like JWTs. However, it increases server calls as the server maintains the session store. This could lead to memory leaks and other issues due to the higher demand on system resources.

🚀 Advantages of JWTs
JWTs are often preferred for applications with a larger user base because the server doesn't need to manage session states for each user. This prevents the server from slowing down under heavy traffic. Additionally, JWTs are particularly useful in Single Sign-On (SSO) scenarios due to their stateless nature, making them a great choice for distributed services and web apps.

Using JWTs leads to more efficient authentication workflows, reduced server load, and a better overall user experience when handling authentication for large-scale applications.
