Password Generator

A good password is long, random and unique. The catch: humans are terrible at randomness. We take the cat name, add an exclamation mark and feel safe. This generator takes that off your hands and rolls real randomness - cryptographically secure via your browser Web Crypto API, not the weak Math.random function.

Three modes cover every need. Password mode builds classic character strings from upper and lower case, digits and symbols, with adjustable length and a selectable character set. Passphrase mode strings together several random memorable words in the "correct-horse-battery-staple" style, in German, English or mixed. Pronounceable mode produces keys you can still type and dictate.

You have full control over the building blocks. Toggle upper case, lower case, digits and symbols individually, supply your own character set, or exclude confusable characters like 0 and O or l and I so the password does not cause typos when copied by hand. For passphrases you set the word count, separator and capitalisation.

Every result is rated instantly. A strength meter, the entropy in bits and an estimated crack time show you in black and white how resilient your password really is - from "cracked instantly" to "longer than the universe has existed". Ready-made presets provide fitting settings for Wi-Fi passwords, PINs, API keys, hex keys and more.

For safe handling afterwards there are two extras: the clipboard can clear itself automatically after 30 seconds so a copied password does not linger forever, and a local history shows you recently generated passwords in case you need one again. Both stay in your browser.

Crucially: no generated password ever leaves your device. There is no server contact, no transmission, no log. The generator runs entirely locally and works offline too - exactly how a password tool has to work to be trustworthy.
