How to use this tool
Password mode
Pick a length (8–64) and which character sets to include. "Exclude ambiguous" removes look-alike characters like l, 1, O and 0 — handy when you'll read or type the password by hand.
Passphrase mode
Generates several random words joined with dashes. Four words from our list gives ~56 bits of entropy; use 5–6 for important accounts. Capitalization and the trailing digit are optional.
The strength meter
The meter estimates entropy — how many guesses a brute-force attack needs on average. Rough guide:
- Weak — under ~45 bits. Don't use for real accounts.
- Fair — okay for throwaway logins.
- Strong — fine for most accounts.
- Excellent — suitable for master passwords and admin accounts.
Keyboard & touch
Everything works with mouse, touch and keyboard (Tab to move, Space to toggle, Enter to press). The Generate button re-rolls; Copy puts the result on your clipboard.
Tips
- Use a unique password per site — a password manager makes this easy.
- Turn on two-factor authentication wherever it's offered.
- Never share a generated password in email or chat.
