Open Password generator →What is the password generator?
A free, private password generator that creates strong random or memorable passwords entirely in your browser. It uses your browser's cryptographically-secure randomness, so the passwords are never sent anywhere and it keeps working offline after the first load.
How to use Password generator
- Pick a style — Choose Random for a string of characters, or Memorable for a passphrase made of real words joined together.
- Set the options — For Random, drag the length slider (8–32) and toggle uppercase, lowercase, numbers, symbols and 'exclude ambiguous'. For Memorable, pick 3–5 words, a separator and whether to capitalise and add a number suffix.
- Generate — Press 'Generate new password' to create one. The strength meter shows how strong it is, and you can keep generating until you like the result.
- Copy or save — Copy the password to use it, or hit 'Save to history' to keep the recent ones in the on-device list.
Frequently asked questions
Is the password sent anywhere?
No. Passwords are generated entirely in your browser using cryptographically-secure randomness and are never uploaded.
What's the difference between Random and Memorable?
Random builds a high-entropy string from the character sets you enable. Memorable joins several real words with a separator, which is easier to type and recall while still being strong.
What does 'exclude ambiguous' do?
It leaves out characters that are easy to confuse, such as 0 and O or 1, l and I, so a written-down password is less likely to be mistyped.
Is my password history private?
Yes. Saved passwords are kept only on your device in this browser, up to the most recent ten, and you can clear them at any time.
How long should my password be?
Longer is stronger. For random passwords aim high on the length slider, and for memorable ones use four or five words; the strength meter helps you judge.
Tips
- Watch the strength meter and aim for the 'strong' band before using a password.
- Use Memorable mode for passwords you must type by hand, and Random for ones stored in a manager.
- Turn on 'exclude ambiguous' for passwords you will read aloud or copy from paper.
- Save a few candidates to history, then pick the one you like best.
