SafeNode Authenticator is a free Chrome add-on designed to enhance online security through TOTP (Time-based One-Time Password) generation. This tool automatically fills in 2FA codes for popular websites, providing a seamless experience while maintaining high-security standards. It integrates with SafeNode's zero-knowledge credential vault, ensuring that sensitive information like API keys, SSH keys, and database passwords are encrypted on the user's device before being uploaded. The application utilizes advanced encryption techniques such as AES-256-GCM and Argon2id to protect credentials, making it a robust solution for security-conscious users.

In addition to TOTP support, SafeNode offers features like secure HTTP proxying for API calls, remote SSH execution, and database queries, all while safeguarding credentials from exposure. Users can manage their vaults efficiently, sharing access with team members while maintaining control through tagging and access logs. The biometrics feature allows for easy unlocking after initial access, enhancing usability without compromising security. With various subscription plans available, including a free tier, SafeNode Authenticator caters to both individual users and teams.
