A password is not as secure as you think it is. Nothing is safe on the internet. Sure, passwords with alphanumeric characters are relatively safe but, how reliable are they? No system is 100 percent secure. But, it is always safer to have added security to ensure that your information is safe. Two-factor authentication adds an extra layer of protection to your login. So, in case you ever get hacked, your hackers will need to use various approaches.
What is two-factor authentication?
Two-factor authentication (2FA) or two-step verification is a process that uses two different information or authentication systems to access a file or service. An everyday example is where you need your Card PIN and an OTP to complete online payments.
What authentication factors can you use?
Authentication factors can range from a password to cellphone approvals or even your current location. There are five important types of authentication factors. However, most two-factor authentication methods rely upon knowledge, inherence, and possession factors.
- A possession factor includes ID card numbers, approval on cellphone, email, or smartphone app.
- A location factor authenticates and verifies your identity using a geographical source using your IP address or GPS data.
- Knowledge factor authentication is one of the most commonly used. It generally includes passwords, shared secrets, and PINs.
- A time factor will restrict your authentication period by permitting and restricting access in a set time frame.
- An inherence or biometric factor is inherent to you. It implies fingerprint, iris scan, and facial recognition. But, it can also include behavioral biometrics like speech patterns, keystroke dynamics, or gait.
A verification system is considered as two-factor authentication only when a combination of factors is used. Using two factors from the same group does not constitute a 2FA. For example, you cannot use a password and PIN for a 2FA. But, you can use a password and your fingerprint or facial recognition, just like how you have on your phone!
Why should you activate two-factor authentication?
Passwords are not foolproof or secure on their own. The cyber attacker can test billions of password combinations in a matter of seconds so, even a complex password is not completely safe. Did you know that over 65 percent of people use one password combination everywhere? It is the digital equivalent of using the same key for your house, car, and safe locker.
Make sure to enable 2FA for your online accounts. It includes online banking, credit card websites, online shopping services (Amazon, eBay, PayPal, etc.), email, productivity apps, password manager, social media, cloud storage accounts, etc.
While no system is fully secure, an added layer of security is always the better choice. Most of the time, 2FA and Multiple factor authentications prevent hackers from hacking you because it takes more time and effort.
