ASP.NET MVC + LiveID --> should I use the Membership provider & Account controller?

I'd like to use LiveID o开发者_如何学运维n an ASP.NET MVC site. Should I still use the ASP.NET Membership provider? How about the default MVC Account controller? I have things working without either, but:

1. Using the Membership controller lets me see when a user last logged in.
2. Using the Account controller makes setting authentication cookies a bit easier.

Thoughts?

Answered here before, Peter Bromberg has a nice sample. You would still use the Membership provider albeit as a custom provider.
