2-factor Authentication and OTP: How SMS Plays a Role in Security

Posted on

SMS goes beyond just being a great marketing tool.

It also allows consumers and businesses to enjoy greater peace of mind when it comes to security. With both sensitive personal and business data constantly under threat from hackers, it’s important that businesses offer a secure means of protection.

Security, OTP, 2Fa

Importantly, SMS has grown to fill this role—providing the tool necessary to keep consumer data safe. Through the use of SMS, businesses can help make sure that their customer data is protected.

By using SMS in your own business, you can better secure your consumers’ data, while also establishing a better record for your brand. This win-win situation reflects why you should start using SMS for security—if you haven’t already.

Below, we’ll explore the different ways that SMS impacts security, looking at the processes of 2-factor authentication and OTP in particular.

What is 2-factor Authentication?

2-factor authentication offers a leg up on traditional online security measures, as users are required to provide two pieces of information in order to enter an account.

For instance, they may need a password, as well as a text code.

Here, you can see how SMS comes into play. Through the use of 2-Factor authentication, businesses can help make sure that consumer information is protected.

With 2-factor authentication, businesses can also help ensure that a user’s account will not be compromised. Under traditional settings, if a hacker managed to secure the username and password of an online user, they would then be able to hack into their account.

However, with 2-factor authentication, this is becoming much more difficult. Instead of just needing a user’s information, they would also need a code texted to the user’s phone.

Presumably, this phone will be on the user—and not on the hacker. This means they would be unable to access the code needed to enter the user’s account. In this way, SMS has become a vehicle for protecting consumer data at some of the world’s most secure institutions. Banks, for instance, use 2-factor authentication on their websites and mobile apps. You may even come across this on other sites when attempting to change sensitive user information—such as a password.

In this way, SMS has worked to provide security to millions of Internet users across the globe. However, the role of SMS in cybersecurity does not stop at 2-factor authentication. It also plays a significant role in OTP.

What Is OTP?

One-time passwords, also known as OTP, provide high-level security. These passwords are generally codes that can be submitted, allowing users to log in one time into a specific site or software.

These generated passcodes ensure that no unauthorized users have access to restricted content. These codes typically get delivered to the phones of authorized users, making them unavailable to anyone else.

This can help protect businesses and the sensitive information they have stored. By utilizing OTP within your own organization, you can better protect your company’s private information—and that of your customers.

If you’ve delved into SMS marketing already, it’s likely that you’ve come across the term “shortlinks” before. But what are they? And how can you cleverly use shortlinks to spice up your marketing campaign?

Take a look below at three ideas that you should consider while planning your own SMS marketing strategy.

  1. See the Number of Clicks allows users to see exactly how successful each link is. This allows businesses to see critical information. For example, you can use shortlinks to measure just how many people are reading your messages, on average, or to see what type of content your contacts are most interested in.

This can be done, of course, by measuring to see which content got the most click-throughs. In doing this, you may find that you need to change up the focus of your marketing strategy to better resonate with your consumers.

Keep in mind, too, that this will allow you to track the base-level health of your overall SMS marketing campaign. For this reason, businesses have made shortlinks one of their top tracking sources for their marketing data—and you should, too.

Even more importantly, however, you can start seeing what your customers are doing after clicking the link. For instance, you may decide to track the number of people who sign up for a promotion or who buy a product.

Additionally, depending on the link, you may even manage to see how engaged your contacts are. Say, for instance, that following clicking the link, customers were prompted to fill out an online form of some kind. This would allow businesses to measure not just the initial interest contacts have in the message’s content, but also how motivated people are regarding the subject.

By using shortlinks to track this data, businesses can get a leg up in their SMS marketing strategies.

  1. Use Links to Track Ad Effectiveness

Perhaps one of the most important and out-of-the-box ways to use shortlinks is to track advertisement performance.

Fortunately, there’s a lot of room in this regard when it comes to businesses. Depending on the type of link sent, businesses have a number of different ways to track the effectiveness of their ads.

For instance, as we’ve noticed, you may have some opt-in promotional only offered through the link. This would offer a very straightforward way of knowing just what type of advertisement content is preferred by your contacts. By collecting an aggregate of this data over time, businesses can start to refine and hone their SMS marketing strategies to be as effective as possible.
