2FA is an extra layer of security to prevent someone from logging in, even if they have your password. To enable your 2FA you only need:
1. Log into your account and go to Account Settings
2. In “Two-Factor Authentication” section, copy and store in a safe place your 2FA Key.
This step is important because it is the only way to recover your 2FA if you lose your phone.
4. Enter in “code” section, the 6-digit code that the app shows you (pay attention because it changes every 30 seconds)
5. Press “Enable 2FA”
