Link-sharing security update to Drive

To make file sharing more secure, a security update changed the URLs for some Google Drive files and folders to include a resource key. This security measure, which appears in a file’s URL, helps protect your file from unintended access. To see if a file URL has a resource key, look for resourcekey=.

About the update

  • If you took no action, the security update impacted certain files and folders in My Drive and shared drives, but not Google Docs, Sheets, and Slides files. 
  • Access to affected files doesn’t change for people who’ve already viewed those files or who have direct access. 
  • By default, most users can remove the update from files that they own or manage. The exception is users in a Google Workspace for Education organization. 
  • Even if you currently have no affected content, impacted files can come to your organization through shared drives or a change in file ownership.

Files and folders used internally 

For any internal sites or documentation that has links, make sure to update those links to new ones that include resource keys. Get the new link from the item’s owner. 


First, Drive notified impacted users of the update and any affected items that they owned or managed. If you let them, your users could decide to remove the update from those items. The update was finished at the end of September 2021.
