10 reasons to add two-factor authentication

why it is important to add two factor authentication

In 2018, there are hardly any people who haven’t heard about two-factor authentication. Yet, not everyone quite understands why it is so important to verify users these days.

In this article, we will cover the top 10 reasons to add 2FA to your app or site.

Fraud Prevention

Every service with account registration and online payments will inevitably become a target of fraudsters. Hacker attacks can be costly to companies so it is better use preventive means and be proactive rather than deal with the consequences after the fact. Two-factor authentication is the perfect tool for exactly that. It helps businesses stop scammers at the door, before they register and do any harm.

Industry Standard

User verification has been added by multiple companies including big enterprises like Google, Facebook, Twitter, Snapchat, etc. It is not just a trend now; it is a must have feature that every app and site is expected to integrate in order to be up-to-date and stay competitive.

Reputation & Trust

Account verification helps create a trusted environment within your app or site. If customers know that a company cares about their safety and privacy, they tend to engage more and take full advantage of its services. At the same time, without two-factor authentication, user accounts can be hacked, resulting in reputational and financial losses, not to mention distrust of your company.

Cost Reduction

When most fraudsters are blocked, businesses do not need to spend as much money to analyze user behavior and track suspicious activities. They also then have less clients to compensate for compromised accounts. By adding Number Lookup to your verification toolbox, you can validate cell phone numbers and further reduce costs by filtering out the incorrect and suspicious ones and not sending them passwords in the first place.

Real Audience

Phone based authentication helps you eliminate fake accounts, thus adding clarity to your real user base. With this info, you can better identify your customers and understand their preferences as well as adjust your marketing campaigns for higher engagement and ROMI.

User Experience

Due to big brands requiring two-factor authentication as a part of their services, most customers have now become used to it, so it does not bother them or cause any friction. With 2FA now being a part of their regular user experience, clients would rather choose services with account verification than the ones without it.


With Number Lookup, it is easy to automatically identify where people are from by the telephone country code. This way, you can be sure you are sending SMS and voice messages with one-time passwords in a language native to users, thus increasing successful login and signup rates.


People carry their phone numbers for a long time and don’t often change them. Thus, in the long term perspective, phone-based authentication is more reliable than other options like email – as customers may forget their email password and completely lose access to it. Phone numbers are also hard to spoof, so two-factor authentication contributes greatly to account security and protects user data.


SMS and Voice are commonly used channels to deliver one-time passwords. They are convenient for customers, as they must simply enter the code in the special field without a need to login into their mailbox and click a link. These channels have high open rates and are very effective at increasing the number of successful verifications.


Two-factor authentication is hard to develop by yourself. You would need to create the entire infrastructure from scratch, make agreements with multiple telecom operators worldwide, and spend a lot of money to finally make everything work. Luckily, this is not the case nowadays with CPaaS providers offering ready-to-use authentication solutions that can be seamlessly added to your app or site with only a few lines of code, using your favorite programming language.
