Frequently asked questions
Are these passwords truly random?
Yes. Passwords are generated using crypto.getRandomValues(), a cryptographically secure random number source built into your browser — not a predictable pseudo-random generator.
How long should my password be?
Most security guidance recommends at least 12–16 characters mixing upper and lower case letters, numbers, and symbols. Longer passwords are exponentially harder to brute-force.
Is the generated password sent to a server or stored?
No. Generation happens entirely in your browser, and nothing you generate is logged, stored, or transmitted.
Should I reuse the same password across sites?
No — use a unique password per account, ideally kept in a password manager, so a breach on one site doesn't compromise your other accounts.
