There are many reasons why data breaches happen, but nearly 86% of data breaches involve stolen credentials (mostly through phishing) and it has become evident that users need more than just a password to secure their accounts. Adding another layer of security, 2 factor authentication, on top of a password helps you mitigates the risk of unwanted access. In this article, we'll go through what is 2 Factor authentication, and what are the best applications you can download & use.
How does 2 Factor Authentication Work
When using 2 factor authentication, a password is no longer the only thing that is needed to get access to the data and even if your password is revealed in any way, no one can access your information. This works by requesting you to enter a random code each time you log in (or try to access/modify your data) and the code is obtained through a specific way (SMS, email, Authenticator apps) and is usually fast expiring.
Your password, even if you pay enough attention to choosing a complex and strong password, can get into the hands of malicious actors through various means, such as a phishing attack or brute force attack. Two-factor authentication mitigates some risks by requiring users to authenticate by means other than a password.
Different Types of 2 Factor Authentication
Two Factor Authentication can be in several types. In some cases, the second authentication is also a PIN or password, it can also be an answer to a security question of which you're the only one who is aware. Sometimes it's a code or link that you receive the in form of a text message on the number that you've previously added to your account or in an email to make sure that it's you. Considering the sensitivity and confidentiality of the data, the second authentication can also involve biometrics such as fingerprint, facial ID, and retina scans. The most usual type of 2FA Authentication, aside from SMS and Email, is software token authentication.
