Frequently asked questionsCommon questions answered

These answers explain common password gen tasks, expected input formats, and edge cases so both visitors and search engines can understand what this tool does.

How random are the generated passwords?

Passwords are generated using the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure randomness — the same source used by password managers.

What does entropy mean?

Entropy measures how unpredictable a password is, expressed in bits. A 128-character set with a 16-character password gives about 112 bits of entropy — effectively uncrackable with current hardware.

Are the passwords sent anywhere?

No. Everything runs locally in your browser. No password ever leaves your device.

How many passwords can I generate at once?

Up to 20 passwords in a single batch using the count slider.
