Generate strong random passwords or memorable passphrases without anything ever leaving your browser. Character mode builds a password from the character classes you pick, at the length you pick, optionally skipping visually ambiguous characters. Passphrase mode draws words from the EFF Large Wordlist (7776 words) so you get something you can actually type or read out loud. Both modes use your browser's cryptographic random source and show the real entropy in bits instead of a vague strength badge.
This tool does not use any data storage or network traffic.
Entropy: —
Words come from the EFF Large Wordlist (7776 words), CC BY 3.0. Capitalisation and the separator are fixed formatting choices, so they add no entropy — only the words, the number and the symbol do.
