Frequently asked questions
What is Bcrypt Hash used for?
Use it to create a hash for a test user or to see the format your login store expects. Store the hash, not the password.
How do I use the free online Bcrypt Hash tool?
Fill in Password. This field is required. Set Cost (4-15). The starting value is 10. Click Run and copy the result under the form.
What can I paste or upload into Bcrypt Hash?
Enter the password and a cost from 4 to 15. The default cost is 10. Higher cost is slower.
What output does Bcrypt Hash give me?
A bcrypt string such as $2a$10$... that embeds the algorithm, cost, salt, and hash. Each run uses a new salt, so the string changes.
Is Bcrypt Hash free, and is my input private?
Yes — Your input is processed in memory for this request only. It is not saved to disk or the database, and it is cleared after the tool finishes.
Why is a second hash of the same password different?
bcrypt generates a new salt every time. Verify with Bcrypt Verify instead of comparing two hash strings as text.
Inputs are processed in memory only and are not saved to disk or the database. Data exists only for the duration of your request.
