Password generator
Strong random passwords, memorable passphrases and PINs. Generated with your browser’s cryptographic random number generator — nothing is sent, logged or stored.

Strength: Very strong117 bits of entropy
What makes a password strong?
Unpredictability, measured in bits of entropy: how many guesses an attacker who knows exactly how the password was made would need. Every extra character or word multiplies that number. The meter shows the entropy of the method — length × the size of the alphabet or word list — not a guess at how “random-looking” the result is.
Random, memorable or PIN?
- Random — letters, plus numbers and symbols if you want them. The strongest per character; best when a password manager remembers it for you.
- Memorable — words picked at random from the EFF’s 7,776-word list. Easier to type and remember; five or six words make a solid master password.
- PIN — digits only, for phone locks and cards where the number of attempts is limited. Never use a PIN as a password.

Everything runs in this page with crypto.getRandomValues, the browser’s cryptographic random source, and unbiased sampling so every character is equally likely. No password ever leaves your device, and the page keeps working offline once it has loaded.
Frequently asked questions
Is it safe to generate a password on a website?
Here, yes: the password is created in your browser and is never sent to a server, logged or stored. You can disconnect from the internet after the page has loaded and it still works.
How long should a password be?
For a random password, at least 16 characters; the default of 20 gives over 100 bits. For a passphrase, five or six words — especially for a password manager’s master password.
Random password or memorable passphrase?
Use random passwords for everything your password manager stores. Use a passphrase for the few you have to type from memory, such as the master password or your computer login.
Is a 6-digit PIN secure?
Only where the number of attempts is limited, like a phone lock or a bank card. Six digits are about 20 bits — far too few for an online account.
