Smart Password Generator is a Chrome add-on designed to create strong and unique passwords for various websites based on a master password and the site's domain. This tool operates entirely within the browser, ensuring that no data is sent to external servers, which enhances user privacy and security. The algorithm used combines SHA256 hashing with base64 encoding to generate a password that is 16 characters long, effectively balancing complexity and usability.

The application emphasizes security by encouraging users to select a strong master password or passphrase, with Diceware being a recommended method for generating robust passphrases. Users should be aware that while the option to remember the master password can enhance convenience, it introduces potential risks if the device is compromised by malware. Overall, Smart Password Generator provides a practical solution for managing passwords securely without compromising user data.
