Strong passwords, made on your device. Never sent, never saved.
Words
Which should I use?
Using a password manager? Pick random characters. You never type them, and they're the strongest for their length.
Need to remember or type it? Pick a passphrase, like for your computer, Wi-Fi, or your password manager itself. Random words are far easier to remember than random characters, and just as hard to guess.
About Password Generator
A simple, strong password generator. Make a random passphrase of real words you can remember, or a random password of letters, numbers, and symbols for your password manager. Every password is made on your device with your browser's cryptographically secure random number generator. Nothing is sent anywhere or saved, not even a history. Passphrase words come from the EFF large word list by the Electronic Frontier Foundation, used under CC BY 3.0 US.
FAQ
Is it safe to make a password on a website?
Here, yes. The password is made in your browser and never leaves your device, and the page can't send it anywhere. To see for yourself, open this page, turn on airplane mode, and keep making passwords: it works the same.
Are passphrases really as strong as random characters?
They can be. What makes a password strong is how it was chosen, not how it looks. Six words picked at random from 7,775 give about 78 bits, which would take thousands of years to guess even in the worst case. Words you pick yourself are much weaker, because people choose common words and patterns.
What does "bits" mean?
It measures how many guesses it takes: each extra bit doubles them. The time shown is the worst case, where a site stored passwords badly, its password file was stolen, and an attacker tries a trillion guesses a second. Guessing on a login page is far slower. Aim for 70 bits or more for important accounts, and 90 or more for things like your password manager.
The site says my password needs a capital and a number. What do I do?
For a passphrase, tick "Capitalize words" and "Add a number". For random characters, keep Uppercase and Numbers on: every type you turn on is always included.
Can I put it on my home screen?
Yes. On iPhone, open this page in Safari, tap Share, then Add to Home Screen. On Android, open it in Chrome, tap the ⋮ menu, then Add to Home screen (or Install app). It then opens like a regular app and works offline.
