How can I implement advanced authentication in PHP?

You can implement advanced authentication in PHP using techniques like OAuth, JWT, and multi-factor authentication.

What are some best practices for securing user authentication?

Best practices include using HTTPS, hashing passwords, implementing rate limiting, and regularly updating your authentication methods.
