Strong random passwords and memorable passphrases
Generate a strong random password or a memorable passphrase in your browser. Use presets for common lengths, or open a fixed-length page for 8, 12, 16, 24, or 32 characters. Optionally include spaces, then copy with one click. Fully client-side.
Characters mode builds a random string from the sets you enable: uppercase, lowercase, numbers, symbols, and optionally spaces. Use the length presets, or open a fixed-length page such as 12 characters or 16 characters when a site requires an exact size. Words mode builds a memorable passphrase from the EFF large wordlist (7,776 words).
Generation runs entirely in your browser with crypto.getRandomValues.
Nothing is uploaded, stored, or logged on a server. Click Regenerate anytime for a new value.
Enable Spaces when a site allows whitespace in passwords.
Exclude ambiguous removes lookalikes like 0, O, l, 1, and I
so passwords are easier to read or type aloud.
No. All generation happens locally in JavaScript. Your passwords never leave your device.
For random character passwords, 12-16 characters with mixed character sets is a solid baseline for most accounts. Prefer 16 or more when the site allows it. For passphrases, six words from a large wordlist is a common recommendation.
Word mode picks random words from the
EFF large wordlist
and joins them, for example ocean-quiet-maple-river.
Passphrases are easier to remember while remaining strong when you use enough words.
Yes. In Characters mode, turn on Spaces. In Words mode, choose Space as the separator. Some sites reject spaces, so check the policy first.
