Frequently asked questions
Is it safe to generate passwords on a website?+
Yes — when the tool runs entirely in your browser. SwiftTooly never sends your password to a server; it is generated locally using the Web Crypto API and only exists in your browser's memory.
What makes a password strong?+
Length is the biggest factor, followed by a wide character set. A 16+ character password mixing uppercase, lowercase, numbers, and symbols is extremely difficult to brute-force.
Should I use a different password for every account?+
Absolutely. Reusing passwords across sites means one breach can compromise many accounts. Combine unique generated passwords with a password manager for best results.
Do you store or log the passwords I generate?+
No. Nothing is stored, logged, or transmitted. Refresh the page and the password is gone — make sure to copy it somewhere safe first.
