What are the best practices for authentication in Go?

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

Can you explain how to securely hash passwords?

You can use libraries like bcrypt or Argon2 to hash passwords securely. They add salt and are resistant to brute-force attacks.

What is multi-factor authentication and why is it important?

Multi-factor authentication adds an extra layer of security by requiring two or more verification methods, making unauthorized access harder.

How can I validate user input effectively?

You can use libraries like go-playground/validator to enforce rules on user input, ensuring data integrity and security.
