What is Two-Factor Authentication (2FA)?

learn about 2fa — how to enable two factor authentication

Much of our daily lives now involve the internet. And all of this web activity often necessitates adding personal or sensitive details to online accounts. Unfortunately, this information is appealing to hackers who typically target businesses in an attempt to steal their customers’ data. While creating strong and unique passwords is good, it’s not always enough to keep information safe.

Different Types of Authentication

What Is Two-Factor Authentication (2FA)?

  • Phone (to receive a text or call with a one-time login code)
  • Authenticator Apps (Authy, Google Authenticator, Microsoft Authenticator, etc.)
  • Personal Identification Number (PIN)
  • Picture and CAPTCHA logins
  • Challenge questions
  • Biometrics (patterns, fingerprints, voiceprints, or iris scans)
  • Hardware Tokens
  • QR Code logins

While not completely invulnerable, it’s less likely an account can be breached when using 2FA. Even if someone had a username and password, they’d also need the other factor that is used to verify the account holder’s identity. The same would apply if a person lost their phone. However, if a lost phone isn’t locked and all passwords are saved, this could be a problem. Luckily, it’s harder to lose an eye or a finger…

How to Enable 2FA

: Not all websites and platforms support 2FA or Multi-Factor Authentication. Be sure to verify that an organization supports all your security needs before signing up for a service.

What is Multi-Factor Authentication (MFA)?

Similar to 2FA, Multi-Factor Authentication requires users to provide extra details on top of their username and passwords. MFA can just take it a step further. It can use all the same identifiers as 2FA but can include additional ones. For instance, MFA could include a username/password, a push authentication (text), and a PIN, or any combination of authenticators.
