2 Factor Authentication

2FA or 2 Factor Authentication or Multi-Factor Authentication I'm sure a lot of people have heard of or been offered to use on certain websites etc.  But what is it? Well, simply put, it is a second security feature or a second password.

Quite a few websites online now are using 2FA, adding that extra level of protection. What it is, is either it can text you a random code, or email you a random code or even use an app called an authenticator.  Some places even have their own 'authenticators'.

Once you sign in to a website with your password, a secondary screen will come up asking for the code. Most of these are time-sensitive as well, with most codes only lasting 10-30 seconds before changing. 2FA has turned out to be quite useful in the security area of online shopping and gaming. As it gives you that 'extra' secure feeling.

If there are sites you visit, that you value, I'd suggest signing up for 2FA if they offer it. That way if your password is compromised, at least they can't log in with it as easily. In the ever-growing area of technology there are many ways that 2FA is evolving as well.  Including facial recognition, thumbprint recognition, and I'm sure retinal recognition will soon be available for everyone as well!
