The secret key (seed) is a unique 16 or 32 character alphanumeric code which is generated during the token enrollment. It is used to generate OTPs - one time passwords. The server and Google Authenticator both know the same secret key and based on it they generate the same OTPs.
Authenticator apps are not vulnerable to this problem, and thus are a more secure way to do two-factor verification. Most of the sensitive accounts you use today already offer stronger 2FA. And there's no shortage of third-party authenticator apps that'll enable it for you.
