Generate a strong password

Make a password that can't be guessed, with the length and characters a site asks for, or a passphrase of random words that's easier to type and remember. It's created by your own browser and never leaves it.

Passwords are generated on this device and never sent or stored.

How it works

Choose Characters or Passphrase.
Set the length and the kinds of characters, or the number of words.
Copy the password, or tap Generate again for another.

Why generate passwords here

Each password comes from your browser's cryptographically secure random generator, the same source browsers use for encryption keys. It is made on your device and never sent to us or anyone else, and nothing is stored: close the tab and it's gone.

How strong is strong enough?

Strength is measured in bits: each bit doubles the guesses an attacker needs. A 16-character password from upper and lower case letters, digits and symbols has about 103 bits; 12 characters give about 77. A passphrase of 5 words from the 7,776-word EFF list has about 65 bits, and 6 words about 78. As a guide, aim for at least 80 bits for email and banking, which is 13 or more mixed characters or 7 words. Length adds strength faster than symbols do.

Using it well

Use a different password for every account, and keep them in a password manager rather than a document. Turn on two-step sign-in where you can. Avoid look-alikes (l, 1, I, O, 0) only if you'll type the password by hand; leaving them in makes it slightly stronger.

Frequently asked questions

Is it safe to generate a password on a website?

Here, yes: it's made by your own browser's secure random generator and never sent anywhere. You can even disconnect from the internet after the page loads.

Characters or passphrase?

Characters for sites with strict rules or a short maximum; a passphrase for passwords you type often, like a computer login or a password manager's master password.

Why does every password include each kind of character I chose?

Many sites require at least one capital, number and symbol, so each chosen kind appears at least once.

Do you keep the passwords?

No. Nothing is stored or logged; each one exists only on your screen until you copy it.
