2FA Increases Security and Can Be Used with Other Methods

2FA, or two factor authentication, is an authentication method which is used by organizations to increase security. This type of authentication can be confused with other methods, such as when a user is asked to create security questions. Security questions are not two factor authentication, but can be used along with this method for added protection. Instead, two factor authentication will ask the user to provide something they possess, such as a digital certificate.

Information Is Inputted in a Specific Order When Using 2FA

When combining 2FA with other security measures, users will input information in a specific order. First, they will provide the appropriate digital certificate to initiate the two factor authentication process. Once the certificate has been validated, they will be allowed to enter in their user name and password. After their log on ID is authenticated, then they can be asked to answer a series of security questions, or input a pin, or other type of information to gain access.
