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
Before you start, download an authentication application such as Authy, 1Password or LastPass Authenticator.
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,
Enter the six-digit code from your code generation app
