FAQ
Where is the password generated?
It is generated in the browser and the result is not sent to a server.
How long should a strong password be?
Use at least 12 characters, ideally 16 or more, with multiple character types.
Are draw results fair?
The tools use the browser cryptographic RNG (crypto.getRandomValues) to produce unpredictable results.
Do identical settings produce identical results?
No. Fresh random values are used on every run, so each run produces different output.
