# Bcrypt Hash Generator

> Hash a password with bcrypt at a configurable cost factor — the right way to store passwords.

To hash a password with bcrypt, enter it above and choose a cost factor. Bcrypt is deliberately slow and automatically salts every hash, so identical passwords produce different results and brute-force attacks stay expensive even with modern hardware.

## FAQ

### Why does the same password give a different hash each time?

Bcrypt generates a new random salt for every hash and stores it in the output. This defeats rainbow tables — the same password produces a different hash for every user.

### What cost factor should I use?

Pick the highest value where hashing still takes under about 250 ms on your production hardware. In 2026 that is typically 12 or 13 for a server, and the tool shows the measured time for each setting.
