Two Factor Authentication With PaylessSMS

Before we see what is meant by 2FA, let us see the reasons behind implementing 2FA

Data breaches are not new but the magnanimity of the breaches is growing each year. In 2014 alone, more than 1 billion personal records were accessed illegally. ( ‘Anthem’ data breach, the IRS data breach are the most recent data breaches that affected thousands of customers in the US. The Amazon password breach and the VTech breach in 2015, has enabled consumers and organizations to step up their authentication processes. (Amazon Forces Password Resets after Possible Security Breach) All these reasons and more necessitate the implementation of two factor authentication that might reduce data breaches related to weak passwords.


What is 2FA?

1. Authentication

2FA is omnipresent in our digital lives without us knowing it. ‘Authentication’ in its simplest form is implemented by the traditional ‘username’ and ‘password’ combination. Most of us have been told repeatedly to keep passwords complicated enough so that it does not get hacked. But having a combination of having upper and lower case alphabets, numbers and symbols for different websites stumps us, more than the hackers! We ultimately forget the different usernames and passwords leaving us annoyed and frustrated. 2FA or ‘two factor authentication’ solves this problem by providing a second layer of security to authenticate the user. In addition to the username and password, we also add a second layer of security in the form of SMS passcodes or hardware tokens or push notifications according to each individual’s smart phone authentication app services.


  • 2FA is implemented by
  • “something you know” (the ‘username’ and password combination)
  • “something you have” (a smartphone that receives SMS passcodes as an example) “Smartphones” fits the bill of “something that you have” since one possesses a smartphone all the time.
  • This second layer of authentication is in tune with the ‘layered security’ approach adopted by security professionals to bolster a personal or professional environment. In a ‘layered security’ approach, even if the first layer of security is compromised, it assumes that the second layer will provide adequate defense, such the resources are not compromised in any way.

3. Types of 2FA authentication:

Hardware tokens”, “SMS notifications” , “Push notifications”, “Phone callbacks”, “Mobile passcodes” and “wearable devices” are a few of the different authentication types. Let us discuss a few of them: Hardware tokens: “Tokens” are generated on a device, which are then entered into the prompt. One of the disadvantages of this type of authentication is that the device that is used to generate the token must always be present with the user. If the token generating device is pressed multiple times, tokens can get out of sync with the one that is needed to login.


Why Do You Need Two Factor Authentication?

Two-factor authentication works as an extra step in the process, a second security layer, that will reconfirm your identity. Its purpose is to make attackers' life harder and reduce fraud risks

Imagine waking up on a splendid spring day, opening your laptop and realising that you can’t access your online accounts anymore. Your email has been breached, your website, your most precious work, is now gone, and your credit card was used for shady transactions.

Two-factor authentication, also called multiple-factor or multiple-step verification, is an authentication mechanism to double check that your identity is legitimate.

How SMS Authentication Works

Let’s say, one of your user has forgotten password and would like to reset them, then the user validates account credentials and then you as a enterprise owner will send an OTP via SMS. User gets a password on phone and enters that to validate further on your website. Thus, you are securing user’s account and user’s transactions.

  • If you have in-house software developers, they can integrate this feature on your website or IVR system. Or you can hire software companies to do the same.
  • Authenticating users using SMS has been the most secured platform for any business. If you are not using this feature, try and implement now.

There’s Power in Triggered Messages!

The average email open rate climbs gradually after sending for about 24 hours. The average SMS open rate spikes, with 70% of opens happening in the first 60 minutes.
This immediacy allows for triggered SMS messages. For example, if you have a regular customer over a period of time, and they stop coming into your store, you can send them a text with deals to get them to come back.
These messages can be triggered by any action (or inaction) by the customer, from not coming to visit your ecommerce shop to buying a particular product. These triggered messages are also great ways to ask for feedback from your customers
This may be the most important tip to follow if you want your SMS campaign to be successful. For one thing, remember that most carriers limit the length of a text message to 160 characters. Besides that, however, the faster you get to the meat of your message, the better.
