Multi Factor Authentication: Why You Need It
Multi Factor, or better called Two Factor Authentication (2FA) by definition is a security measure. It's a process that allows users to provide two different methods of authentication to verify themselves. This is as an added layer of security when logging on to a site. Whether it's an app, social media site or any site/application that requires users to login.
With the rise in cybernetic crimes, one way of verifying a user's credentials is not enough. Especially if there's sensitive data; such as credit card information, social security numbers and more.
This could lead to identity theft. With stolen credentials, a hacker can do a lot of damage to the consumer. From loss of money in their bank account, to their credit scores plummeting.
Companies have stepped up in the past by requiring stronger passwords from their users. In addition, having a second factor authentication helps strengthen security.
2FA is a way to confirm that the person is the user of the account; after a login and password has been provided.
2FA adds an additional step that can validate the user. There are several ways to provide a second layer of authentication. From a PIN number, to using an Authenticator app or text message that provides a temporary code.
Different authentication options
Below are several options to add as a second actor authentication:
- Security Questions - this was one of the first methods of 2FA; where users could select a question, and provide an answer, as a second method of authentication.
- SMS Verification - Many companies such as Paypal, Google and others send a message to an SMS with a temporary code.
- Email Verification - The system sends a code or link to verify the user.
- Authentication apps - Apps such as Duo, Google Authenticator, designed to provide a temporary passcode to use as a 2FA.
- Biometry - Biometry uses biological data; for example scanning a fingerprint to login to a computer.
Even if there isn't sensitive data in a web application, it is strongly recommended to provide some type of second way to authenticate a user. This provides the user with feeling safe in using the application.
