Download and install a two-factor authenticator app on your smartphone if you don't already have one. Popular choices include Google Authenticator, Microsoft Authenticator, and Authy.
From the main navigation bar, click on your profile avatar in the top right corner and select "My Profile" from the dropdown menu.
On your profile page, find the "Multi-Factor Authentication" section and click the "Set up 2FA" button.
You will be taken to the 2FA setup page. Open your authenticator app and scan the QR code displayed on the page. If you cannot scan the QR code, you can manually enter the provided key into your app.
After scanning the QR code or entering the key, your authenticator app will generate a 6-digit verification code. Enter this code in the confirmation box on the setup page and click "Set up".
Once completed, you will be prompted to enter a code from your authenticator app each time you log in, adding an extra layer of security to your account.
