Use a unique password for every account
Long, random passwords resist guessing and credential stuffing. Store them in a reputable password manager, enable multi-factor authentication, and never reuse passwords across services.
Frequently Asked Questions
Are passwords sent to the server? +
No. Generation uses the browser Web Crypto API and passwords remain in the page only.
What length should I use? +
Twenty random characters is a strong general default; use the maximum allowed by the target service.
Why exclude ambiguous characters? +
It makes passwords easier to read or transcribe by removing characters such as O, 0, l, 1, and I.
What does entropy mean? +
It estimates the search space based on password length and character pool size.
