Two-factor authentication, also commonly referred to as 2FA is an optional feature for extra-strong security. It adds another layer of security to your account so if compromised or stolen, only you can log in.
Enabling Two-Factor Authentication
Go to your Account Settings and scroll down to Account Security.
You will see if it is enabled or disabled in the brackets
Click Enable Two-factor Authentication to open a pop-up window,
Scan the barcode with your application
Enter the six-digit code from the application (After scanning the barcode image, the app will display a six-digit code that you can enter below)
You will see a new window appear with recovery codes.
Save the codes by downloading them in TXT format, printing or/and copying them to the clipboard.
Recovery codes should be only used to access your account in the event you cannot receive two-factor authentication codes from your app.
Two-Factor Authentication in Use
If two-factor authentication has been enabled, you will be asked for the security code after logging in with your e-mail and password.
Go to the login page,
