2FA (Two Factor Authentication)
2FA (Two Factor Authentication) is a process that uses two steps to authenticate a user.
Rather than just asking for a single piece of information to verify a user, an additional step is added. Such as using a temporary identity token good for minutes, vs. a forever password, that is sent to a cell phone or from an authenticator and is required to access an account.
Often, a third-party authenticator (TPA) app enables two-factor authentication, usually by showing a randomly generated and frequently changing code to use for authentication.Back to Glossary
