## Description

The TOTP Authenticator Chrome extension seamlessly transfers two-factor authentication (2FA) codes from your mobile device to your browser, eliminating the need to manually type authentication codes. By integrating with the TOTP Authenticator mobile app, this extension enhances account security by providing instant access to time-based one-time passwords (TOTP) used by numerous services like Google, Facebook, GitHub, and Epic Games.

Two-factor authentication significantly boosts your online security by requiring a temporary, algorithm-generated code in addition to your password, helping prevent up to 80% of cyber attacks. This extension acts as a convenient supplement to the mobile app, streamlining your login process across supported platforms. Detailed setup instructions are available at the official guide.
