About this tool
Get a password that no one could guess, made in your browser with its secure random generator. Pick a length and the kinds of characters to use, and every kind you tick is guaranteed to appear. You can leave out look-alikes such as O and 0, make a whole list at once, and see how many bits of entropy each password has.
Common questions
Is the password stored or sent anywhere?
No. It is made on your device and exists only on this page. Nothing is sent or saved, apart from your settings in your own browser.
How long should a password be?
At least 16 characters for important accounts. Length matters more than symbols, and a password manager means you never need to remember it.
Are the characters really random?
Yes. They come from the browser's secure random source, and each one is picked with equal chance, with no bias towards some characters.
Is it free to use?
Yes. There's no sign-up, and you can use it as often as you like.
Is my text uploaded anywhere?
No. This tool runs inside your browser, so what you enter stays on your device.
Do I need to install anything?
No. It works in your browser on a computer or a phone.
