Why is our password generator safe?
Hardware-grade CSPRNG
Uses the browser's window.crypto.getRandomValues to produce unpredictable values.
Air-gapped from any server
No data is sent to a server, API, or logging service, and the tool works fully offline.
Accurate entropy calculation
Each password's entropy is computed from its length and the size of the character set.
Frequently asked questions about password security
How is this different from Math.random()?
Math.random is not suitable for security; this tool uses the browser's Web Crypto API directly, so its output is not designed to be predictable.
How long should a standard password be?
At least 16 random characters is recommended for general use; more length increases the key space and resistance to guessing.
Is a multi-word passphrase secure?
Yes. Random 4- or 5-word passphrases are both secure and memorable thanks to their length and huge number of combinations.
Why is there an option to avoid similar characters?
To prevent mistakes when reading or typing characters such as 1 and l, or 0 and O.
