Passwords, passphrases and API keys

Everything is generated in your browser with the system's cryptographic random generator (crypto.getRandomValues). Nothing is sent to or saved on the server.

Entropy calculated on the chosen structure. For passwords with all character classes enabled it is slightly lower than the value shown, because at least one character per class is guaranteed. Passphrases use the BIP39 list (2048 words, 11 bits per word).
