KeyMaker is a lightweight, open-source browser extension that creates unique passwords for each website based on information you already know. The same inputs will always generate the same password, making it easier to remember and reproduce passwords without storing them. How It Works: 1. Enter the website or service name. 2. Enter one or more keywords. 3. Select the toggles to use different parts of the keyword or the entire keyword. 4. Click Generate Password. 5. Save your pattern with the "Save pattern" button. 6. On any future sign-up or login, KeyMaker will detect the password field, automatically use the current site's domain, apply your saved pattern, and offer to fill the password in one click. Security All password generation happens locally in your browser. KeyMaker does not: Store passwords Send data to external servers Require an account Collect analytics Your inputs never leave your device.
