There's no reason you shouldn't have 2FA in the first place unless you don't have a phone. People have been begging to get 2FA on Bitcointalk to prevent account theft since I joined the site in early 2015; it's absolutely great that Fortunejack offers 2FA for account security. Even if you're absolutely sure your password is secure, always enable 2FA. It's a great last line of defense to stop anyone that wants to get into your account, and if you write down the backup code for Google (or basically any other 2FA application) 2FA and store it in a safe place, unless you lose the code and your phone there's no way you'll lose access to your account on the 2FA side of things.
