Two-factor authentication is a type, or subset, of multi-factor authentication. It is a method of confirming users' claimed identities by using a combination of two different factors: 1) something they know, 2) something they have, or 3) something they are. A third-party authenticator (TPA) app enables two-factor authentication, usually by showing a randomly-generated and constantly refreshing code which the user can use. - Wikipedia
