Generated password
Estimated search space: about 0 bits. This is an estimate, not a breach-resistance guarantee.
The practical guide
Create a random password from the character sets you choose.
Length and character choices affect the possible search space, while the browser cryptographic random source selects the characters without a server request.
Randomness and strength
A longer password drawn from several allowed characters is generally harder to guess, but site rules, reuse, phishing, and storage practices still matter.
Handle generated passwords safely
The tool does not save results. Copy them only into a trusted password manager or the intended account, and avoid reusing them elsewhere.
Privacy by architecture
Your files and tool inputs stay in your browser.
The selected files, inputs, settings, and outputs are processed in this page and are not uploaded to any server.
Questions, answered
Frequently asked questions
Are passwords generated with Web Crypto?
Yes. The tool uses the browser cryptographic random source.
Are generated passwords stored or uploaded?
No. They remain only in the current page unless you copy them elsewhere.
Does every website accept every symbol?
No. Adjust character sets to match the destination password policy.
Does the strength label guarantee safety?
No. It is a practical estimate and cannot account for reuse, compromise, phishing, or how the password is stored.
