To protect our personal information online and keep them private, we need to make sure we're the only ones able to access them. That is done through the process called authentication. You need to correctly »introduce« yourself to the service and prove that you're really you before you can enter.
There are three widely accepted methods of authenticating yourself:
- Knowledge – something you know. Passwords, PIN numbers and patterns to unlock your smartphone all fall into this category. It's a simple, yet not very secure method. Much has been written about the problems with »strong« passwords, people using the same password for different services and similar issues, so at this point, we just want to emphasize that passwords can be problematic.
- Possession – something you own. Smart cards, tokens, similar devices, and in simplified terms also your phone. These types of authentication are commonly a part of the multifactor authentication process.
- Inherence – something you are. Biometric types of authentication fall into this field –fingerprints, facial scans, retinal scans, voice patterns etc. The jury is still out on the pros and cons of this type of authentication, mostly because it opens a whole new field of privacy issues, poses high costs and is still not 100% hack-proof.
What is Two-Factor Authentication?
Two-factor authentication (2FA) is a very efficient way to secure your accounts and digital assets. It's like a extra layer of protection. It combines the password (something you know) with a second factor, like a one-time passcode or push notification sent to your mobile phone (something you own).
Note: You will also see names like Two-Step Verification, Multifactor authentication and similar. While there are certain technical differences between them, at this point we won't get into details.
Why does it matter?
As we have established, passwords are weak and even the most complex ones don't necessarily protect you from hacking attacks. Two-factor authentication requires two different keys to log you into your account, significantly decreasing the risk of account takeovers. Using a Two-Factor Authentication process can help avoid identity theft, as well as phishing via email because the criminal would need more than your name and password.
Online security experts strongly suggest enabling 2FA on all your online accounts; including email accounts, social networks, online banking, e-commerce sites, cloud computing etc.
