Importance Of 2FA | How To Enable 2FA

Two-factor authentication (2FA), sometimes referred to as two-step verification or dual factor authentication, is a security process in which the user provides two different authentication factors to verify themselves to better protect both the user’s credentials and the resources the user can access.

Two-factor authentication provides a higher level of assurance than authentication methods that depend on single-factor authentication (SFA), in which the user provides only one factor — typically a password or passcode. Two-factor authentication methods rely on users providing a password as well as a second factor.

Two-factor authentication adds an additional layer of security to the authentication process by making it harder for attackers to gain access to a person’s devices or online accounts, because knowing the victim’s password alone is not enough to pass the authentication check. Two-factor authentication has long been used to control access to sensitive systems and data, and online service providers are increasingly using 2FA to protect their users’ credentials from being used by hackers who have stolen a password database or used phishing campaigns to obtain user passwords.

 

 

PriorityEx has adopted the Google authenticator app and we shall explain its advantage

1. It’s More Secure

Google authenticator is surprisingly most secure one of all the other options available to receive verification code for 2-step verification. I’ll call it the safest option for 2 reasons:
  • Reason #1: It works inside a secure box. Receiving verification codes through SMS is not as secure as using the authenticator. As many of the apps on your device may have permission to access your SMS and bad apps can see your codes. And the same with backup codes that you print on paper are prone to be seen by someone.Unlike SMS option and backup codes, Google authenticator app works independently and inside a box so no other apps can see your codes and no person can see them as long as your device is secure.
  • Reason #2: New code every 60 seconds. The code you receive through SMS generally is valid for about 30 minutes and the backup codes you generate work for several days. So these codes may be stolen and it would be serious threat for your account. But Google authenticator uses the TOTP (Time-based One-Time Password) algorithm and gives a new code every 60 seconds, so each code expires in just 60 seconds which make it a secure option to generate codes for 2-step verification.
 

2. It Works without Internet and Network coverage

The most interesting thing about Google Authenticator is it doesn’t require any sort of internet and cellular connectivity
When I first enabled 2-step verification to secure my google account, I was worried about how would I able to get the code when I am out of network coverage area and internet connectivity for my mobile, but Google authenticator app solved both the issues. With this app on your mobile, you don’t need any internet or even a SIM card on your mobile.
The science behind it is, Authenticator app mechanism is built using a special algorithm called Time-based One-Time Password algorithm. With TOTP, the same code will be generated both on your mobile and on Google side without the need of internet. So the code matches and you get into your account.

3. It is EASY to use

Two factor authentication, keeps your account safe but also make your login a little complex, especially waiting for the SMS with a verification code. Even though you will receive codes pretty quick, but sometimes it may be delayed due to some technical and network errors.
But in Google authenticator, the codes are ready to be used and most importantly it works even in Airplane mode.
Apart from this the app is easy to use with simple interface. The app also works on older versions of android (Android 2.2 and above) and is less than 2 MB in size, so it instantly fires up and works smoothly even on the devices with less amount of RAM and storage.
