OneFactor is a free Chrome add-on designed to enhance security through two-factor authentication (TOTP). This tool integrates seamlessly into your browser, ensuring that your authentication codes are generated securely and stored locally. With a focus on user privacy, OneFactor employs robust encryption methods to protect your data, requiring a personal master password for access. The application supports easy management of TOTP accounts, allowing users to add, edit, or delete entries effortlessly.

The interface is user-friendly, featuring a clean popup that supports both light and dark modes, making it accessible for various preferences. Users can also reorder their entries through a simple drag-and-drop function. OneFactor is designed with no tracking, ensuring that your usage remains private. Recent updates have improved the import functionality and allowed for the addition of codes from other authenticator apps via QR codes.
