What is two-factor authentication and how could it benefit you?
Two-factor authentication, put simply, is entering in two different passwords to achieve one purpose. For example, you can setup two-factor authentication for accessing your bank account online. What that means is you will enter your email or username and password as normal. Then, the second factor (i.e. the second password you enter) is one that is generated on a personal device such as your cell phone.
The benefit is that you are using two passwords. Also, this second password is constantly changing, let’s say on average every one minute (the frequency can be customized). From a security standpoint, you are much more protected using this method.
Why? For one, your main password is still in place. Someone looking to breach your account would need that password. However, even if someone were to get your password, they would not easily get past the second layer. If you set up two-factor authentication on your phone, they would need your phone too in order to get into your account.
There is much more security using this method. For personal accounts, important data and more, this would be a great investment to get setup.
You might be wondering what would happen if you lost your phone. How could you get into your own accounts? Those scenarios do occur, but precautions are there for when and if this happens. There are typically one-time use backup passwords to get into your personal accounts for emergencies. Those should be kept in a secure place, memorized, and/or not ever lost.
