Passkey is an app that sits between your DVD &/or Blu-ray drives & everything else in Windows. What it does is decrypt discs with DRM, so you can copy the disc, or play a retail video DVD or Blu-Ray disc using any media player that can handle the format, & so on.
Passkey does contact the mothership for information on just how to decrypt individual discs, but even so the software is updated fairly frequently to handle new protections, e.g. v. 9.01 was available 9/3, with v. 9.02 released 9/6. The main new feature of version 9 however seems to be how it's activated -- instead of the keys that were sent out for v.8, 9 requires a sign-in to an account at DVDFab's site. Version 8 will presumably no longer be updated, or at best not often before updates stop entirely
Now the main reason for this post is that thousands, maybe 10s or hundreds of thousands of lifetime keys for Passkey 8 were given away in August, 2015. As of this afternoon those licenses are not recorded in their database the way that purchases are, so if you install 9, it will by default replace v.8, but if you attempt to activate 9 it will show a trial ending next month.
Giving DVDFab the benefit of the doubt, they did not have accounts available at their site before this, AFAIK. So it could be an oversight -- or not -- but I would guess that there's going to be an awful lot of pressure from everyone who got a free lifetime license for DVDFab to honor the lifetime part. I imagine we'll just have to wait & see if DVDFab decides to make those v.8 licenses work in 9.
