The MFA (Multi-Factor Authentication Assistant) is a Chrome extension designed to simplify the multi-factor authentication process by automatically retrieving and filling in MFA codes. This tool enhances user experience by eliminating the need to manually check emails for codes, thereby saving time and minimizing errors during authentication. It uses secure OAuth access to fetch codes from your Gmail account, ensuring a seamless and secure operation.

Key features include client-side processing, which keeps your authentication credentials secure, and optional email forwarding for added security. The extension maintains authentication for up to an hour, with an option for longer sessions using a Cloudflare Worker to obtain a refresh token. As an open-source project, it allows users to verify its security measures, making it a reliable choice for both developers and professionals who frequently engage in multi-factor authentication.
