2 Factor Authentication(2FA) in separate table - MVC

Hi,

I added the 2 Factor Authentication(2FA) with Google Authenticator by following this website and it works.

Now I would like to have a separate table for 2FA because I will have other type of authenticator. I don't want to add a new column in the user table each time I have a new authenticator.

How do I do that?

Thanks for your help
