How to Fix Microsoft SharePoint Keychain Prompt Repeatedly Appearing on Mac

Product: Microsoft Office for Mac
Device & OS: macOS
Scenario: Using Microsoft Office applications linked to a SharePoint or Microsoft 365 account on a Mac.
Observed behavior: The macOS system repeatedly asks for permission to use 'Microsoft Organization Credentials' in the keychain, interrupting the workflow.

Before you start

Ensure your macOS and Microsoft Office applications are updated to the latest versions, and make sure you know your current Mac login password, as it is required to modify keychain settings.

Solution 1Recommended

Clear Microsoft Credentials from Keychain Access

Removing corrupted or outdated Office credentials forces your Mac to request fresh authentication, resolving the repeated prompt loop.

The repeated SharePoint prompt usually occurs when Microsoft Office's stored security tokens become out of sync with your Mac's keychain. Clearing these specific entries allows Office to recreate them cleanly.

Quit all Office applications

Make sure all Microsoft applications (Word, Excel, PowerPoint, Outlook, and OneDrive) are completely closed on your Mac.

Open Keychain Access

Press Command + Space to open Spotlight search, type 'Keychain Access', and press Return to launch the utility.

Search for Microsoft credentials

In the search bar at the top right of the Keychain Access window, type 'Microsoft Office'. You will see items like 'Microsoft Office Credentials' or 'Microsoft Identity'.

Delete the credential entries

Select the Microsoft-related credential items, right-click (or Control-click) on them, and select 'Delete'. Confirm the deletion if prompted.

Restart and sign in

Restart your Mac, open any Microsoft Office application, and sign in again with your Microsoft 365 credentials to rebuild the keychain tokens.

Clear Microsoft Credentials from Keychain Access

No Data Loss: Deleting these keychain entries will not delete your documents or emails. It only resets your stored login sessions.

Solution 2

Contact Microsoft 365 Administrator or Support

Use this solution if resetting your local keychain does not stop the SharePoint credential prompts.

Frequently Asked Questions

Why does my Mac keep asking for my keychain password for Microsoft Office?

This typically happens if your Mac keychain is locked, your macOS user account password was recently changed, or the stored Microsoft credentials have become corrupted. The system repeatedly prompts for access to confirm your identity.

Will deleting Microsoft credentials from Keychain Access cause data loss?

No, deleting credential entries from Keychain Access is safe. It only forces Office to prompt you to sign in again to regenerate a fresh, uncorrupted security token. Your actual documents and settings remain unaffected.

How do I grant 'Always Allow' to Microsoft SharePoint in the keychain?

When the prompt appears, you can enter your Mac's login password and click 'Always Allow'. If the prompt continues to appear even after clicking 'Always Allow', it indicates a corruption in the keychain entry, which must be deleted and recreated.
