An Overview of Google Authenticator
Google Authenticator is a mobile authentication application developed by Google. It uses Time-based One-Time Passwords, or TOTP, to add an extra layer of account security. The app generates six-digit verification codes that refresh every 30 seconds, making each code short-lived and unique. It supports Google accounts as well as many third-party websites, services, and online platforms.
Google Authenticator is available for Android and iOS devices. After the initial setup, it works offline and does not require an internet connection to create codes. Users can set up accounts by scanning a QR code or entering a provided key manually. This process helps reduce the risk of unauthorized access to online accounts during everyday login attempts.
