Turning on 2FA provides added security for your account, and is recommended for all users.
To set up 2FA, browse to your settings page and select "2-Step Verification" on the left side. Click to turn on and scan the QR code with Google Authenticator, Authy or other OTP app. Enter the generated code and 2FA will be turned on.
While you're here, download a set of backup codes which will give you access if you ever lose access to your phone or authenticator app. Ensure you safeguard these codes as they will allow someone to bypass the 2FA on your account.
