What is two-factor authentication and why your business needs it

Two-factor authentication is two passwords instead of one. Something you know (your password) plus something you have (your phone). Even if someone steals your password, they can't log in without your phone. Every business should turn it on for email, banking, and cloud storage because it blocks 99% of break-ins.

Hackers can steal passwords, but they can't steal your phone sitting on your desk. Two-factor authentication adds a second barrier. After entering your password, you get a code on your phone that you type in to finish logging in. This simple step stops hackers cold. For any account that matters to your business, two-factor authentication should be turned on.
