Frequently asked questions
Are these passwords actually random?
Yes. They come from crypto.getRandomValues, the browser's cryptographic random source, not Math.random. Generation happens locally and no password is ever transmitted or logged.
Should I use a random password or a passphrase?
A passphrase of four or more words is easier to type and remember while being just as hard to guess. Use random characters where a site imposes a length limit, since entropy per character is higher.
Are my files uploaded when I use Password Generator?
No. Password Generator runs entirely inside your browser. Your file is read locally, processed on your own device, and handed straight back to you. You can confirm this yourself: open your browser's developer tools, watch the Network tab, and run the tool — no request carries your data anywhere.
Is Password Generator free?
Yes, completely. No account, no sign-up, no watermark on your output, and no cap on how many times you can use it. The project is open source under the AGPL licence.
Does Password Generator work offline?
Mostly. The site caches itself after your first visit, so it keeps working without a connection. Tools that need a specialised library — PDF editing, OCR, QR codes, MP3 encoding — need a connection the first time you run them, then that library is cached too.
