G Authenticator is a Windows desktop authenticator designed for users who rely heavily on Google accounts, Google 2FA, and Google-style sign-in workflows. It provides a desktop-first way to generate one-time passwords locally on your PC, making two-factor authentication easier to manage during daily Windows use.

The app allows you to add Google-related 2FA accounts by scanning QR codes directly from your screen, without using a phone or external camera. All authentication data is stored locally on your device, giving you full control over your account management and helping maintain privacy during long-term use.

G Authenticator is built for clean, focused desktop workflows, offering a distraction-free interface for managing multiple 2FA accounts efficiently
