What this tool does

Strength comes from length and from the size of the character set, and the entropy figure below shows the combined result in bits. Characters that are easy to confuse, such as l, I, 1, O and 0, are left out so the password stays readable when you type it by hand.

How to use it

  1. Drag the slider to choose a length.
  2. Switch character sets on or off; more variety means higher entropy.
  3. Press Regenerate until you are happy, then copy the password.

Privacy

This tool runs entirely in your browser. Your input is never uploaded, stored or shared — closing the tab removes it.

Frequently asked questions

Is the password stored or sent?
No. It is generated with crypto.getRandomValues in your browser, is never transmitted, and disappears when you close the tab.
How long should a password be?
Aim for at least 75 bits of entropy — with all four character sets enabled that is roughly 12 characters, and 16 or more is better.
