What are the best practices for authentication in MVC applications?

Some best practices include using secure password storage, implementing multi-factor authentication, and validating user input.

Can you explain why multi-factor authentication is important?

Multi-factor authentication adds an extra layer of security by requiring users to provide two or more verification factors.

What methods can I use for secure password storage?

You should use hashing algorithms like bcrypt or Argon2, along with salting to protect passwords.

How can I ensure user input is validated?

You can use server-side validation, client-side validation, and libraries that help sanitize inputs to prevent attacks.
