Enabling Two-Factor Authentication
For added security, you can optionally enable two-factor authentication on your account. Once enabled, you'll be required to enter a one-time code provided by an authentication app (such as Google Authenticator, Authy, or any other app that supports TOTP authentication) each time you log in.
Open the Dashboard.
Click your Account avatar in the corner.
Click Security.
Under Two-Factor Authentication, click Enable
Follow the on-screen instructions to enable two-factor authentication on your account.
(Optional) On your Account Security page, click Backup Codes to view and print your two-factor authentication backup codes. In the event you are unable to access your authentication app, these one-time use codes can be used to log you in instead.
You're done! You will now be prompted for a one-time code (provided by the authentication app) each time you log in. If at any point you want to disable two-factor authentication on your account, simply visit your Account Security page and click Disable
