So long as the phone number and/or recovery email address you used when you signed up for it are still active. My uncle was unable to remember his password after he had moved. He cancelled his phone and internet services, and was unable to get his password reset when he finally got hooked back up to the internet. In theory, it works great. In practice...maybe, maybe not.

For the average home user, I agree. For a techie with the right tools, it's like a walk in the park.

If the software allows it, would it make it easier to simply set up a schedule that allows for connectivity between 9:00am and 11:00am on Sundays?

This may be an excellent option, provided they can either learn to modify the schedule on their own, or count on a techie type to be there for them when they're needed...
