G regenerate · C copyWhat makes these passwords secure?
V2 uses your browser’s Web Crypto API for randomness. Every password that satisfies your chosen rules is equally likely. Longer passwords offer more possible combinations. Use a different password for each account and keep them in a password manager.
Can anyone see what I generate?
No—ComplexPass does not receive, store, or share the passwords and passphrases you generate. Generation happens entirely in your browser, and the generated values stay on your device. If you copy or download a result, it is saved to your device’s clipboard or a local file, so keep those private. Anyone who can see your screen or access your device could still see your passwords.
Password or passphrase?
Passwords work well with a password manager. Passphrases combine randomly selected words and are helpful when you need to type or remember a secret. Six random passphrase words are a good starting point.
Where did the original version go?
Still here, blue background and all. Use Classic v1 at the top of this page for a little nostalgia. V2 is the default and uses modern cryptographic generation.
