Have you ever been asked to provide a user name and password when logging onto a website? This type of authentication is referred to as single sign on authentication. If you were also asked to provide a pin number, token key or other form of secondary authentication, then you experienced 2FA or two factor authentication. This type of authentication creates a more secure environment for access data, especially for data contained on the Internet.
2FA Is an Effective Security Option for Different Online Applications
The Internet is a public forum which by itself is not a secure environment. Security is created using different types of security, such as SSL, certificate authority, and 2FA. Two factor authentication is effective for a variety of different online applications and functions, including cloud computing, online banking, SaaS applications, VPNs and VOIP. As increased security is needed online, two factor authentication has become more common.
