Frequently asked questions
Are these passwords secure?
Yes. They are built with your browser's cryptographically secure random number generator (crypto.getRandomValues), not the predictable Math.random.
Are my passwords stored anywhere?
No. Everything happens locally in your browser — nothing is sent to a server or saved.
What makes a strong password?
Length plus variety. Aim for 16 or more characters mixing uppercase, lowercase, numbers and symbols.
Should I reuse passwords across sites?
No. Use a unique password for every site and keep them in a reputable password manager.
