To activate 2FA, follow these steps:
1. From the homepage, click on "Account" located at the bottom right of the page.
2. Select "Two-Factor Authentication".
3. If you don't have a 2FA application yet, download one.
Then, click on "Set up".
4. Open the authentication application and enter the key or scan the QR Code to get your temporary code on the 2FA application. Be sure to keep the backup key safe, as it will allow you to connect your 2FA to another device in case of loss or damage to your phone.
Finally, enter the 6-digit code displayed on the authentication application and click "Enable 2FA" to complete the process.
