What is two-factor authentication?

Sometimes called 2-factor authentication, or 2FA, two-factor authentication uses at least one backup method as protection when you're logging in somewhere. You often just need a username or email address and a password to sign in to the websites and apps where you store all sorts of personal information. 2FA adds a step that hopefully makes it harder for hackers to get that info.

Your Amazon account may have multiple credit cards on file and yours and all of your family members' addresses. If someone is able to access that account with just your email and a common password, they will have access to not only your personal information, but also your money.

Two-factor authentication has become a standard security setting in the workplace, as offices want to provide extra protection on company-owned devices, especially outside the workplace as remote jobs continue to grow in popularity. Now, you can also set up two-factor authentication on all of your popular social media websites and other commonly used sites like major banks.

How does two-factor authentication work?

Once you've logged into the website you'd like to set up 2FA on, you can choose a backup method where you'll have to approve any login.

For example, picture your Amazon account. If you don't want anyone on a new device to be able to log in to your Amazon account using just your email and password, you'll want to set up two-factor authentication. Then you'll pick a backup method, like receiving a text with a code anytime someone tries to log in from a new device.

Why should I enable two-factor authentication?

While it might seem annoying to follow a few extra steps to log in to any of your major accounts, it’s worth it to protect your information from anyone else. Two-factor authentication means you have to approve a login on one of your approved devices or via a method like texting, which makes it much harder for hackers to log in to any of your accounts.
