What are the best practices for storing hashed passwords?

What are the best practices for storing hashed passwords?

The best practices include using a strong hashing algorithm like bcrypt, salting passwords, and using a unique salt for each password.

Why is salting important in password hashing?

Salting adds a unique value to each password before hashing, which helps protect against rainbow table attacks.

How often should I update my hashing algorithm?

You should consider updating your hashing algorithm whenever a new, more secure algorithm becomes available or if vulnerabilities are discovered.

Can I use SHA-256 for password hashing?

While SHA-256 is a strong hashing algorithm, it's not recommended for password hashing alone. Use bcrypt or Argon2 instead.

What should I do if a password is compromised?

If a password is compromised, immediately reset the password, notify users, and consider implementing additional security measures like two-factor authentication.
