PDFs showing up in Google Search

Some of linked PDFs are showing up in Google Searches as static1.squarespace.com linked files. Even though my Squarespace site is behind a password protected wall, people are still able to access these files if they pull up on the search.

I have tried:

• Changing Page Settings > SEO and toggling the 'Hide Page from Search Results'.
• Code Injection - injecting noindex code into the header
• Submitting removal requests on Google Search Console. However, static1 linked documents/images would not apply in this scenario)

These documents contain sensitive information. Is there any other advice you could walk me through to removing these documents/images from the Google Search parameters?

Correct. Although "on-page" content - the text on a Squarespace page - is protected when it is behind a site password or a Member Area login, the same is not true for files that you upload to your site, like PDFs. These are stored on a global Content Delivery Network (CDN) and not behind the password or login.
