Two-factor authentication is a technology used to create an extra layer of security on your accounts, regardless of type – banking apps, social networks, delivery, and even on the Weni Platform.  

With the advancement of cybercriminals’ abilities, data leakage, and fraud, you need to keep your accesses protected. 

Follow this article and understand the technology behind this security and how to enable your two-factor authentication on Weni Platform. 

What is two-factor authentication?

Two-factor authentication is a system for identifying users on various types of accounts, websites, applications, software, and platforms. 

It is called an extra layer of protection because it prevents inappropriate access – either from malicious people or just because others cannot access certain information. 

Therefore, this is an extremely important technology when we think about data leakage, especially when there is loss of devices such as computers and cell phones, or even remote intrusion into your devices. 

How does two-factor authentication work? 

Also called 2FA, two-factor authentication works from two stages of verifying your identity in order to gain access to your account. Typically, the first stage of identification is a login and password. 

The second stage of authentication varies depending on the type of service you are accessing, and can be a PIN, code sent by email or SMS, and even a photo or biometrics. 

Do I really need two-factor authentication? 

Yes! With the increasing agility of hackers and other malicious people, having only your password as a form of access protection is no longer enough

In this sense, two-factor authentication works like a protective vest. So even if someone finds out your password, they will not be able to access your account if this second layer of identification is in place. 

This is an even more important factor when we consider that many people shop or access band applications over public wi-fi networks. When this habit is added to a weak password, the exposure to cybercriminals is even more. 

However, it is important that you do your part and help this technology. Do not share passwords and authentications with others and never click on links from social networks, or WhatsApp that you have not requested. 

Some criminals send login links to fake pages so they can access your accounts – a practice called phishing

Types of two-factor authentication 

The three types of two-factor authentication are: 

  • biology;
  • knowledge; 
  • possession. 

Biological 2FA is one that requires facial recognition, voice recognition, biometrics, fingerprinting, or even eye-retina scanning (if you have the necessary scanning devices). 

In knowledge-type two-factor authentication the identification is done by asking questions that only you can know. For example, a code received on your computer or cell phone, registered information . 

In the possession model, authentication may require you to plug in a USB token or have your credit card in hand, for example. 

Types of authenticators in 2FA

In the authentication types different authenticators can be used, these are:

  • SMS;
  • email
  • push notifications;
  • location;
  • software tokens (applications you need to have installed, usually on your computer)
  • physical tokens (or hardware token) (devices you connect before logging in). 

How do I enable two-factor authentication? 

To enable two-factor authentication, or confirm that it is already enabled, simply access the privacy settings of your applications and systems. 

If you are unable to access this information, be sure to contact the online service support and see if 2FA is available for your devices.
