Device & OS: Mac
Scenario: Using a Mac and encountering persistent keychain credential prompts from Microsoft services.

Remove Obsolete Microsoft Credentials in Keychain Access

Clear old or corrupted Microsoft Office and OneDrive keychain entries to stop the recurring SharePoint prompts.

This recurring prompt usually occurs when macOS retains outdated or conflicting Microsoft Office credentials. Deleting these obsolete entries forces the system to request a fresh authentication, eliminating the persistent pop-up.

Open Keychain Access

On your Mac, open Spotlight Search by pressing Command + Space, type 'Keychain Access', and press Return.

Search for Microsoft entries

In the search bar located at the top right of the Keychain Access window, type 'Microsoft', 'Office', or 'OneDrive'.

Delete obsolete credentials

Locate any obsolete or duplicate entries related to Microsoft Office or SharePoint. Right-click (or Control-click) these outdated entries and select 'Delete'.

Restart and sign in

Restart your Mac, then open any Microsoft application. You will be prompted to sign in again with your current credentials, which will create a fresh, error-free keychain entry.

Proceed with Caution: Only delete entries you are sure are no longer needed. Deleting active credentials will require you to sign back into all your Microsoft apps, which could cause temporary sign-in interruptions.

Frequently Asked Questions

Why does Microsoft SharePoint want to use my confidential information?

Microsoft applications occasionally need to verify your account status in the background. If the saved login token in your Mac's Keychain becomes corrupted, duplicated, or outdated, the system continually prompts you for permission to access the credentials.

Will deleting Keychain items delete my Microsoft files?

No, deleting items in Keychain Access only removes your saved passwords and authentication tokens. Your documents and files stored on your Mac or in cloud storage remain perfectly safe.

What should I do if I don't use Microsoft services anymore?

If you have migrated to another platform and no longer use Microsoft services, you should uninstall the Microsoft Office suite and OneDrive from your Mac. Afterward, you can safely remove all related Microsoft entries in Keychain Access to prevent future pop-ups.

Can I use WPS Office to open my existing Microsoft Office files on Mac?

Yes, WPS Office natively supports Microsoft Office file formats. You can seamlessly open, edit, and save your existing Word, Excel, and PowerPoint documents on your Mac using WPS Office.
