Question details

- Product
- Device & OS
- not provided
- Scenario
- Sharing a PDF document via a cloud link for viewing or reviewing.
- Observed behavior
- Recipients are unexpectedly asked to enter sign-in credentials when trying to open the shared PDF link.
Check the current storage location of your PDF file and verify whether you shared the document for simple viewing or collaborative review.
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.
Check if your PDF is saved on a public cloud service, SharePoint, a WebDAV server, or a local network folder.
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.
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.

Share PDFs Easily with WPS Office
WPS Office provides a built-in cloud service that allows you to generate secure, customizable sharing links for your PDFs. You can easily set permissions so recipients can view or comment without needing to create an account or sign in.
- 1. Open the PDF in WPS Office: Launch WPS Office and open the PDF document you want to share.
- 2. Click Share: Navigate to the 'Share' button located in the top right corner of the interface.
- 3. Adjust Link Settings: Select 'Create Link' and choose your preferred permission settings, ensuring you select 'Anyone with the link can view' to bypass sign-in prompts.
- 4. Copy and Send: Copy the generated link and send it to your recipients. They can open it directly in their web browser.

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.
