With this update, the search advertising giant is adding a resource key to sharing links, which will impact access to the files for those users who haven’t yet viewed the files.

“Once the update has been applied to a file, users who haven’t viewed the file before will have to use a URL containing the resource key to gain access, and those who have viewed the file before or have direct access will not need the resource key to access the file,” Google said in a note accompanying the update.

Google Workspace admins have until July 23 to decide whether or how to apply the security update within their organization. In the Alert Center, they can view how many files, folders, shared drives, and users are impacted.
