Well, why not 7 days?

  The advantage of a smaller time period is obvious: if 7 days is secure, then 7 hours is more secure. But presumably there's a good reason they chose that number, I'm just wondering why that might be.

    I assume it's a number they chose to strike a balance between security and eventualities that create support burdens. It could probably be user-defined, but when it comes to setting a one-size-fits-all default and offering users an option, Apple usually selects the former.

    It seems a reasonable default, but would be nice if there was a custom setting for a shorter time frame.
