What Is 2-Step Verification / Two Factor Authentication (2FA)?

2FA which we all know and might have seen online is an authentication process that grants a user access into a website or an app after he or she has provided one or two pieces of evidence that clarifies them to be the person in possession of the account or profile they want to gain access to in a website or an app.

2-Step Verification or 2FA is a security protocol issued by most websites and applications, they offer more security protection to one’s online accounts and platforms like Facebook, Google, Microsoft and even Apple recommends 2FA to their users. A 2FA enabled account will require an extra confirmation from either an SMS sent to the registered phone number, email or even the 2FA App linked to the account.

Why Is It Important To Activate 2-Step Verification on Your Google Account?

2-Step Verification can be very annoying at times but it’s very important to have it linked to your Google Account, and below are some of the importance of activating 2-Step Verification on your Google Account.

  1. Extra Security – You might be thinking you have the strongest password combination that no hacker can guess but sometimes it takes a Phishing Link to get your password stolen. But when you have 2FA enabled on your Google Account, even someone with your password won’t be able to access your Gmail unless they provide the code sent to your 2-Step Verification linked email or phone number.
  2. No Need for Complicated Passwords – In as much as Google recommends using a strong password combination which is often good, but sometimes people go too far by using passwords they can’t remember. But with a 2-Step Verification, you can easily set a non-complex password and use the 2FA as a backup for it.

Why Can’t Google Recognise My Nigerian Phone Number?

The reason why Google can’t recognize a Nigerian number is that Nigeria wasn’t listed among countries that can use the 2-Step Verification. But that was a long time ago because even now Nigerians still can’t use the 2-Step Verification.

But the reason behind the “Invalid number, try again” error is still unknown but there’s a theory backing this “Invalid number, try again” and that is (“Invalid number, try again” mostly occur on a Google Account that is less than 6 months or 1 year). However, this theory was long nullified because the Google 2-Step Verification still won’t work on my personal account that’s more than a year old.

From a more personal perspective, I suspect that the inability of Nigerians to link their phone number to Google 2FA has a connection with the high rate of fraudulent activities emanating from Nigeria, nevertheless, do let me know if you have a contrary opinion using the comment box below.

Now back to the reason for this article, there’s a solution here and you’ll get to know how to resolve Google 2-Step Verification through the steps below.
