Two-Factor Authentication (2FA) adds an extra layer of security to your online accounts by requiring not just a password but also a second form of verification. Google Authenticator is a popular app for this purpose. This guide will walk you through the steps to set up 2FA using Google Authenticator.

2. Navigate to the security settings. This can usually be found under "Account Settings" or "Security."
