How Two-Factor Authentication Works and Why You Need It Right Now

☝️ Your password alone might not be enough to keep hackers out. Two-factor authentication adds a second layer of protection that stops intruders even when they know your password. I'll explain how it works, why you need it, and how to set it up without making your daily log-in a hassle.

☝️ Two-factor authentication
Two-factor authentication (2FA) adds something you have (like a mobile device) or something you are (like your fingerprint) to something you know (your password) to confirm you are authorized to access an account. Losing your second factor is not a deal-breaker, and there are ways to make two-factor less intrusive in day-to-day use. If you have 2FA enabled, hackers can’t get in, even if they know your password.
