Frequently Asked Questions
How long should my password be?
Aim for at least 12–16 characters for anything important. Length matters more than complexity — a long random password is far harder to crack than a short one packed with symbols.
Is this generator actually secure?
Yes. It uses your browser's built-in Web Crypto API to generate cryptographically random characters — the same technology used for secure cryptographic operations, not a predictable pseudo-random function.
Does the password ever leave my device?
No. The password is generated entirely in your browser and never sent to a server. Once you close or reload the page, it's gone unless you've copied and saved it yourself.
