8 Best Two-Factor (2FA) Authentication Apps to Protect Your Email and Social Media

It’s a good idea to have passcodes sent to your phone, but new keys and softwares can make the practice much easier and safer. What a ridiculous thought, right? The stories of people having their accounts hacked are commonplace in today’s environment. Safety and privacy online are now major concerns. Cybersecurity requires more than one layer of defense. A complicated password does a good job of protecting your information, but it can be broken as well. This article will list down some of the best two-factor authentication apps for you.

How does two-factor authentication apps work?

In order to keep your online accounts safe, a security mechanism known as two-factor authentication (sometimes called two-step verification) can be enabled.

Rather of relying on just a single piece of information, like a password, to prove your identity, two-factor authentication apps makes use of both your existing password and a temporary One-Time-Password (OTP) sent to you via text message or email.

Let’s have a look at this illustration to clarify things. How strict are the criteria for accessing your inbox?

  1. Your email address
  2. Your password

Single Step Verification describes this method. We just need to enter our credentials and we’ll be in. But do you realise how risky this procedure may be? Your email address is easily accessible to the public. Hackers can actually access your account if your password isn’t strong enough!

This led to the development of two-factor authentication apps. No one else can access your accounts, even if they know your email and password. Using two-factor authentication (2FA) increases security by requiring you to log in with credentials that only you, the real user, have access to. Your private information will be safe from prying eyes this way. Two-factor authentication is currently supported by several widely-used platforms, making logins to them far more secure.

While there are a variety of 2FA methods available, they all follow a similar procedural flow. Common steps in a two-factor authentication deal are as follows:

  1. To access the site or service, the user must input their credentials.
  2. First, the password is checked by an authentication server; if it’s valid, the user moves on to the second verification step.
  3. The authentication server sends a one-of-a-kind code to the user’s second-factor device.
  4. A user’s identity is verified upon successful completion of the further authentication.

While most MFA providers use similar back-end processes, there are numerous different MFA implementations, and not all of them are created equally.

Types of Two-Factor Authentications

Let’s check out how some of the most widely-used platforms these days are adopting two-factor authentication.

  • Email-based 2FA
  • SMS-based 2FA
  • Voice-based 2FA
  • Software token 2FA

The aforementioned authentication methods are used by a variety of businesses and services to further protect their clients and customers.
