Google knew about the problem of guessable secret links for a while and changed the way link generation works back in 2017 (presumably for Drive, too?). Of course, that doesn’t affect links you’ve shared in the past, and soon Google is going to require your old links to change, which can break them. Google’s new link scheme adds a “resourcekey” to the end of any shared Drive links, making them harder to guess. So a link that used to look like “https://drive.google.com/file/d/0BxI1YpjkbX0OZ0prTHYyQ1U2djQ/” will now look like “https://drive.google.com/file/d/0BxI1YpjkbX0OZ0prTHYyQ1U2djQ/view?resourcekey=0-OsOHHiQFk1QEw6vIyh8v_w.” The resource key makes it harder to guess. If you head to drive.google.com/drive/update-drives in a browser, you should be able to see a list of your impacted files, and if you mouse over them you’ll see a button on the right to remove or apply the security update. “Applied” means the resourcekey will be required after September 13, 2021, and will (mostly) break the old link, while “removed” means the resourcekey isn’t required and any links out there should keep working. YouTube is also making similar changes. “In 2017, we rolled out an update to the system that generates new YouTube Unlisted links, which included security enhancements that make the links for your Unlisted videos even harder for someone to discover if you haven’t shared the link with them,” says YouTube in a support page.
YouTube creators can decide to opt out of this change. They also have the option of making Unlisted pre-2017 videos public or re-uploading as a new Unlisted video at the expense of stats.
