Two Factor Authentication Apps: Protecting Data [2023]

What is Two-Factor Authentication?

Two-factor authentication often referred to as two-step verification, is a security feature that defends your online versions by adding a layer of security. Instead of using a single factor to verify your identity, such as a password, it uses two, and a one-time password (OTP) sent to you via SMS or email.

Let’s take an example for better understanding. What are the requirements to log in to your email account?

• Your email address
• Your password

It is called one-step verification. All we have to do is arrive at the credentials and log in. But do you know how complicated this process can be? Anyone can get your email address, and hackers can access your account if your password is not strong enough. (If it’s “123456”, you’re in grave danger!)

How does 2FA Work?

Different 2FA methods use other processes but share an everyday standard workflow.

A 2FA transaction generally works like this:

• The user enters their credentials for admission to the website or service.
• An authentication server confirms the password, and also if correct, the user qualifies for the second factor.
• The authentication server affixes a unique code to the user’s second-factor device.
• By confirming the extra authentication, the user validates their identity.

While the underlying processes of multi-factor authentication are essentially the same from vendor to vendor, there are many ways to implement them, and not all approaches are created equal. Let’s look at the dissimilar types of 2FA.
