Frequently asked questions

Yes. Every password is generated inside your browser using the Web Crypto API, the same cryptographic random source used by modern browsers. Your password never leaves your device, so it cannot be intercepted, logged or stored anywhere.

We recommend at least 16 characters for strong protection. NIST now advises against forced periodic rotation; instead use long, random passwords and a password manager. 20+ characters with mixed character classes is excellent for high-value accounts.

Yes — enable 'Exclude similar characters' to remove ambiguous ones such as lowercase l, uppercase I, digit 1 and 0, making passwords easier to type and read aloud.

Use a trusted password manager (Bitwarden, 1Password, KeePass) so you only need to remember one master password. Never reuse passwords across accounts.
