How can I improve authentication security in my Ruby on Rails app?

You can enhance authentication security by implementing features like two-factor authentication, using secure password hashing, and ensuring session management is robust.

What libraries or gems do you recommend for two-factor authentication?

I recommend using the 'devise' gem along with 'devise-two-factor' for easy integration of two-factor authentication.

How can I securely store user passwords?

Use bcrypt for hashing passwords, as it provides a strong level of security and is widely used in the Rails community.

Are there any best practices for session management?

Yes, ensure that you use secure cookies, set appropriate session timeouts, and consider implementing session invalidation on logout.
