Hey team

I recently configured two factor authentication for my microsoft account.

I was wondering if this automatically makes my skydive two factor secure?

Reason being.. I am still using SkyDrive and it hasn't asked me to authenticate.

Also, do I need to connect my Microsoft Account with Skype in order for two factor authentication to work for skype? (And.. will it work with Skype for Windows Desktop? (NOT the windows 8 app))?

Thanks for any tips
