Solution 1Recommended

Verify the PDF Storage Location and Sharing Method

Determine if the PDF is hosted on a platform that inherently requires authentication, such as SharePoint or a private network folder.

The requirement for recipients to sign in heavily depends on where the PDF is saved and how the review was initiated. Public cloud services often allow guest access, while enterprise servers enforce strict authentication.

1
Identify the hosting platform

Check if your PDF is saved on a public cloud service, SharePoint, a WebDAV server, or a local network folder.

2
Review Document Cloud links

If the file is hosted in a standard document cloud service, recipients can usually open the link and add comments using browser tools without signing in.

3
Check enterprise server requirements

If the PDF is hosted on SharePoint, WebDAV, or an internal network folder, recipients will be required to enter their sign-in details to access the file and join the review.

Frequently Asked Questions

Can I share a PDF for review without requiring recipients to sign in?

Yes, if you host the PDF on a cloud service that supports guest access, such as WPS Cloud, recipients can usually view and comment using their browser without creating an account.

Why does my SharePoint PDF link ask external users for a password?

SharePoint and WebDAV servers are enterprise environments that typically require authentication for security purposes. External users will need guest credentials or specific permissions granted by your IT administrator.

How do I change a restricted PDF link to a public one?

You need to adjust the sharing settings in your cloud storage provider. Change the access level from 'Restricted' or 'Specific People' to 'Anyone with the link' to remove the sign-in requirement.
