What is Two Factor Authentication And How Does It Protect Your Business?

Unfortunately, online security breaches are not uncommon these days. That’s why it’s never been more important to ensure all your accounts are as protected as possible.

Strong passwords are important here. (If you have something obvious like “password 1234,” it’s time to change it.) But it’s also a smart idea to enable two-factor authentication on your accounts, which adds a layer of security on top of your password to help prevent unwanted activity.

What is two-factor authentication?

Two-factor authentication (also known as 2FA or multi-factor authentication) requires you to confirm ownership of two separate variables — your password and something else (usually a unique code) — to complete sensitive actions on your account.

Typically you receive a one-time code via email or text message (SMS) as an added verification step. You may have used an authenticator app (like Google Authenticator) that generates 2FA codes on your mobile phone.

Because the codes are different for every single request, two-factor authentication makes it a lot more difficult to hack your accounts (as it’s likely only you have access to your email or mobile device).

At Square, two-factor authentication is required for your most sensitive account changes. For example, when you link a new bank account or reset your password, you are first prompted to log in with your username and password and then required to verify your identity with one-time code sent to your email or with a code from an authenticator app to complete the action.

How do you enable two-factor authentication?

You can opt to enable two-factor authentication in the settings or security sections of most online services (like Gmail, Apple, and Amazon). In addition to the two pieces of information needed to make sensitive changes to your account, Square’s POS system also allows you to enroll in 2-Step Verification.

With this feature enabled, each time you log in to your Square Dashboard you’re prompted to enter your credentials (username and password) as well as a unique verification code sent via SMS.
