How to Fix SharePoint Anonymous Link Asking for Sign-In from a Bookmark
Question details
A user's SharePoint link configured for anonymous access asks for authentication when opened from a saved browser bookmark, even though it works correctly when clicked from an email.
- Product
- Microsoft SharePoint
- Device & OS
- not provided
- Scenario
- Accessing a shared SharePoint document or library via a saved browser favorite/bookmark.
- Observed behavior
- The browser prompts the user to sign in instead of granting anonymous access to the file or folder.
Ensure you have access to the original anonymous sharing link provided via email and verify that the link has not passed its expiration date.
Update the Bookmark with the Exact Sharing Link
Browsers often save the base SharePoint site or library URL instead of the specific anonymous sharing token, causing a sign-in prompt. Replacing the bookmark URL resolves this.
When you click an anonymous sharing link, SharePoint sometimes redirects the URL in the address bar. If you bookmark the page after this redirect, the browser saves the secure library URL rather than the tokenized link that grants anonymous access.
Open the original email or message containing the working SharePoint link. Right-click the link and select 'Copy link address'.
Locate the saved bookmark in your browser's favorites bar or bookmark manager. Right-click the bookmark and select 'Edit'.
Clear the existing URL in the bookmark editor, paste the original anonymous sharing link you just copied, and save the changes.
Click the newly updated bookmark to verify that the file or library opens without requesting a Microsoft sign-in.
Verify Sharing Link Permissions and Expiration
Confirm that the link is still valid and organizational policies haven't restricted anonymous access.
Test Alternative Browsers and Clear Cache
Isolate the issue by testing the link in a different web browser to rule out caching or session conflicts.

Frequently Asked Questions
Why do some SharePoint anonymous links work while others ask for sign-in?
This usually depends on how the link was generated and organizational policies. Links explicitly set to 'Anyone with the link' grant anonymous access, whereas 'People in your organization' or 'Specific people' links will always prompt for sign-in. Additionally, tenant-level admin settings can override specific link settings.
How do I correctly bookmark a SharePoint file without requiring login?
You must bookmark the exact sharing URL provided by the sender. Avoid letting the page load fully and then bookmarking the resulting URL in your address bar, as SharePoint often redirects the tokenized link to a secure backend URL that lacks the anonymous access token.
Can a SharePoint administrator disable anonymous links?
Yes. SharePoint administrators can configure tenant or site-level sharing settings to restrict external sharing. If they disable 'Anyone' links, previously generated anonymous links will immediately stop working and prompt external users to sign in.
