Google Authenticator is a software-based authenticator by Google. It implements multi-factor authentication services using the time-based one-time password (TOTP; specified in RFC 6238) and HMAC-based one-time password (HOTP; specified in RFC 4226), for authenticating users of software applications.
A third-party authenticator app enables two-factor authentication in a different way, usually by showing a randomly generated and constantly refreshing code which the user can use, rather than sending an SMS or using another method. A big benefit of these apps is that they usually continue to work even without an internet connection.
In any case, the authenticator is a multi-factor cryptographic authenticator that uses public-key cryptography to sign an authentication assertion targeted at the WebAuthn Relying Party. Assuming the authenticator uses a PIN for user verification, the authenticator itself is something you have while the PIN is something you know .

A security token is a peripheral device used to gain access to an electronically restricted resource. The token is used in addition to, or in place of, a password. [1] Examples of security tokens include wireless keycards used to open locked doors, a banking token used as a digital authenticator for signing in to online banking, or signing a transaction such as a wire transfer .
