Password Generator: your questions answered
Is my password sent anywhere?
No. Every password is generated entirely in your browser using the Web Crypto API — nothing is transmitted, logged or stored on a server.
Does this check my password against known breaches?
No. This tool only generates random passwords from the character sets you choose and estimates their theoretical strength from length and variety — it does not check against real-world breach databases.
Privacy
