Frequently Asked Questions
What cost factor should I use?
Cost 10–12 is recommended for production use. Higher costs are more secure but slower. Cost 14 takes several seconds.
Is my password sent to a server?
No. Bcrypt hashing and verification run entirely in your browser using bcryptjs.
Can I verify existing hashes?
Yes, switch to the Verify tab, enter a plaintext password and a bcrypt hash, and the tool confirms whether they match.
