Frequently asked questions
Why does it matter that passwords are truly random?
Humans are terrible at choosing random passwords. We gravitate toward patterns, words, and dates that attackers actively target. A cryptographically random password removes all predictability, making brute-force and dictionary attacks statistically infeasible.
Is my generated password saved anywhere?
No. Passwords are generated entirely in your browser using window.crypto.getRandomValues. Nothing is sent to any server, logged, or stored. The password disappears the moment you close or refresh the page.
How should I store the password I just generated?
Use a dedicated password manager for day-to-day storage. For the logins your household shares, Notenz keeps them with the contract they belong to, shared with your partner. Your documents and notes are encrypted.
