Yes, they are internet based but the one issue with that is the level of security they have bumped up. Its great to know it is secure but unless you can access your email account to verify the IP address you are using, you cant log on. I am lucky I have a laptop so i can take it with me but if I tried to log on from a PC than I would have to log in, wait for an email, and link in using the email in order to access it. If I just had my outlook set for emails rather than having a internet based email host I would be screwed and unable to get in.
