Make a list
Generated on your device with crypto.getRandomValues. Nothing is sent or stored. Passphrases use the EFF long word list (7,776 words).
A username that does not contain your name, birth year or town keeps your accounts harder to link and your security answers harder to guess.
Make a list
Made on your device from a hand-picked list of friendly words. Nothing is sent, so names are not checked against existing accounts.
Has this password appeared in a data breach?
Optional, and only when you press the button. Your password never leaves this device: it is turned into a SHA-1 fingerprint here and only the first 5 of its 40 characters are sent to Have I Been Pwned. The list of matching fingerprints comes back and is compared on your device.
Strength
How to use it
- Choose how many words.
- Pick a separator and whether to add capitals and a number.
- Copy it into your password manager or write it down somewhere safe.
Questions
How many words do I need?
Each word from the 7,776-word EFF list adds about 12.9 bits. Five words give about 64 bits, enough for most accounts; use six or more for a password manager or disk encryption.
Where do the words come from?
The Electronic Frontier Foundation's long word list for dice-generated passphrases (2016). Words are picked with crypto.getRandomValues instead of dice.
Do you see or store my passphrase?
No. It is generated inside your browser and never leaves your device.
Can I make several at once?
Yes. Use Make a list to generate a batch with the same settings, then copy them or download a text file.
