Bidvest Insurance outlines what Two-Factor Authentication (2FA) is. Two-Factor Authentication (2FA) is an important tool for securing your digital devices, like your cell phone and digital accounts, including your banking applications.
Two-Factor Authentication, or 2FA, is a multi-factor authentication (MFA) that strengthens account security by verifying your identity, using two different methods. This extra layer of security is used to securely access an online account. While the two-step verification process may sometimes feel like a hassle, it’s important for staying safe online.
How does 2FA work?
When securing an account, 2FA uses two different authentication techniques that are completely different to each other. Usually, in addition to providing your typical username and password, a second authentication method is required. You will then need to provide a verification code using a device that is currently in your physical possession, such as your mobile phone.
Why is 2FA important?
Your data is no longer safe on the internet. Cyber criminals are constantly trying to gain access to your personal information. Securing this information by merely using one password is no longer sufficient.
If someone were to take control of an account that was protected by 2FA, they would be unable to access your account unless they knew the second access factor, which is usually something like an SMS or email verification code.
If your only protection against a hacker or cybercriminal who wants to sell your personal data on the dark web is a simple password, then you don’t stand much of a chance. Simple passwords are useless, because hackers are always developing new methods to crack even the most complex ones. 2FA provides you with double protection against cyber attacks.
Everyone needs 2FA
You don’t need to be rich and famous to be an attractive target for hackers. Hackers tend to target anyone who’s accounts and passwords are not secure. You could be happily scrolling through your Facebook Newsfeed one day, and then be completely locked out the next. If you want to protect yourself, you need additional security. 2FA can go a long way in protecting your accounts. Anything from social media, to iCloud, to your banking accounts, should all be secured by 2FA.
