Authentication Strategies for Modern Apps

Authentication is a critical component of any web application. Let's explore different authentication strategies and their pros and cons.

JWT Authentication

JSON Web Tokens (JWT) are a popular choice for authentication. They're stateless, can contain user data, and work well with microservices architectures.

OAuth 2.0

OAuth 2.0 is an authorization framework that allows users to grant limited access to their resources on one site to another site without sharing their credentials.

Session-Based Authentication

Traditional session-based authentication uses cookies to maintain user sessions. This approach is simple to implement but can have scalability challenges.

Passwordless Authentication

Passwordless authentication methods, such as magic links and one-time codes, eliminate the need for passwords, improving security and user experience.

Conclusion

Choosing the right authentication strategy depends on your application's requirements, security needs, and user experience goals. Often, a combination of approaches works best.
