How the secure password generator works

Generate a password from the character sets you select. Generation uses your browser's Web Crypto random source and does not log, store, or transmit the password.

Method and assumptions

Figur uses browser Web Crypto (getRandomValues) to select characters without bias from the chosen sets, guarantees at least one character from each selected set, and shuffles the result locally.

  • Security depends on the browser providing Web Crypto and on keeping the password secret.
  • Figur never logs, stores, or transmits the password; it is generated only on your device.
  • The chosen length must allow at least one character from every selected set.

If you copy the password, the clipboard may be read or retained by other apps, extensions, or sync services. Paste it, then clear the clipboard when appropriate.

Frequently asked questions

Is the password sent anywhere?

No. It is generated locally in your browser and this calculator does not log, store, or transmit it.

Why include every selected character set?

Ensuring each selected set appears makes the generated password match the options you chose.
