Frequently Asked Questions
What cost factor (rounds) should I use?
10 is the recommended default for production use. It balances security and performance. Higher rounds increase security but slow login. Never use below 8 in production.
Why does bcrypt produce different hashes for the same input?
Bcrypt automatically generates a unique random salt for each hash. This means the same password produces a different hash every time, which prevents rainbow table attacks.
