Today’s Cybersecurity Lesson: 2-factor authentication
As you might expect, there are TWO parts to 2-factor authentication.
1) Something you know (like a password)
2) Something you have (like a phone) to verify your identity.
You type in your password like normal, then you confirm that it’s really you trying to sign in, usually through a text message or authenticator app. This one-two punch of cybersecurity makes it much harder for bad guys to steal access to your accounts.
Password theft is one of the most common forms of cyberattack, but with 2-factor authentication, even IF a hacker gets ahold of your password, they won’t be able to access your account without the second factor. This increased peace of mind makes it well worth the extra time it takes to sign in. Many online services offer 2FA as an option, including Google, Facebook, Microsoft, Apple, probably your bank…
Are there drawbacks? Well, it does usually mean that you’re more dependent on your mobile device. If you lose your phone, that could mean—at least temporarily— losing access to your accounts. You’ll need to make sure there’s a way to recover access, either through backup codes or some other account recovery process.
And we don’t want to lull you into a false sense of security. 2-factor authentication ISN’T a 100% guarantee of safety. Attackers may still be able to bypass this kind of security by stealing your phone number through SIM swapping or other nefarious means. The bad guys are always out there, working overtime. But 2-factor authentication is one of the simplest and most effective ways to add an extra layer of protection to your online identity and personal data.
