Two-factor authentication (2FA) is a security feature that requires users to provide two separate pieces of evidence in order to gain access to an account or service. The two pieces of evidence could be a combination of something the user knows, something the user has, or something the user is.
Most commonly, users are required to enter a username and password, and then receive a one-time code via text message or app. This code is found in the user’s authentication app, such as Google Authenticator or Authy. The code must then be entered into the website or application in order to complete the authentication process.
Many popular websites and applications offer two-factor authentication as an additional layer of security for their users. Google, Twitter, Facebook, and other popular sites all offer 2FA as an optional feature. To set it up, you will need to visit the security settings of your account and follow the instructions to enable 2FA.
To get two factor authentication, you need to sign up for an authentication service provider such as Google Authenticator, Authy, or Duo Security. Depending on which one you choose, you may need to download an app to your phone or tablet and then set up an account associated with that service. Once you have done so, you can create two factor authentication codes and use them when logging into secure websites or other services that require two–factor authentication.
