Dear Lifehacker, My work wants me to enable two-factor authentication on my phone, but it seems risky. What happens if I lose my phone? Will I lose my entire account? And if I change phones, how do I move the authenticator to a new device?
Two-factor authentication is one of the most important security features you can enable. We’ve had it on Apple IDs for a while, but it didn’t work with all Apple services and apps. Today, Apple enabled the feature for iMessage and FaceTime.
