Frequently Asked Questions
What is Bcrypt?
Bcrypt is a secure, adaptive hashing algorithm based on the Blowfish cipher. It includes a built‑in salt and a cost factor that makes brute‑force attacks computationally expensive.
What cost factor should I use?
For most applications, a cost factor of 10 is recommended. It offers a good balance between security and performance. Higher values (11–12) are more secure but slower.
Is my password stored?
No. The password is generated on the server, sent to your browser, and then discarded. We do not store any generated passwords or hashes unless you explicitly create an account and save them.
How is strength calculated?
Strength is based on a score that considers password length and the variety of character types used (uppercase, lowercase, numbers, symbols). A score of 10+ is considered Strong, 6–9 is Medium, and below 6 is Weak.
