The user needs to resolve an issue where Microsoft applications continuously request keychain access for Organization Credentials.

How to Fix the Microsoft Organization Credentials Keychain Prompt on Mac

Product: Microsoft Office (Excel), Microsoft To Do
Device & OS: macOS
Scenario: Launching or using Microsoft applications like Excel or To Do on a Mac device.
Observed behavior: The system repeatedly prompts for the macOS keychain password to access Microsoft Organization Credentials, and the prompt reappears even after entering the password, while the specific credential entry remains invisible in Keychain Access.

Before you start

Ensure you have your macOS administrator password and your Microsoft account login credentials handy, as you will need them to verify account changes and manage your keychain.

Solution 1Recommended

Reload Affected Applications and Reset Microsoft Account Password

This is the recommended method to resolve the authentication loop causing the repeated keychain prompts by refreshing your login token.

Often, the authentication token saved in the macOS keychain becomes desynchronized from the Microsoft server.

By fully closing the applications and forcing a new password update on your Microsoft account, the applications will generate a fresh credential token upon the next login.

Close Affected Applications

Quit Microsoft To Do, Excel, and any other open Microsoft applications by right-clicking their icons in the Dock and selecting 'Quit'.

Verify Your Microsoft Account

Open a web browser, navigate to the official Microsoft account page, and sign in to verify your account status is active.

Update the Account Password

Navigate to the security settings of your Microsoft account online and change your password to force a global sign-out of cached sessions.

Relaunch and Sign In

Open Microsoft To Do or Excel again. When prompted, enter your new Microsoft account password to establish a fresh keychain entry.

Reload Affected Applications and Reset Microsoft Account Password

Resolution Confirmed: Reloading the applications and updating the password resolves the looping prompt behavior, allowing normal operation.

Solution 2

Clear General Microsoft Credentials from Keychain Access

If the specific 'Organization Credentials' entry is hidden, clearing other Microsoft Office credentials can trigger a fresh login prompt.

Frequently Asked Questions

Why does the Microsoft Organization Credentials prompt keep reappearing on my Mac?

This continuous loop typically happens when the authentication token saved in the macOS keychain becomes corrupted or desynchronized with Microsoft's servers, causing the application to repeatedly fail its background security check.

What if I cannot see 'Microsoft Organization Credentials' in Keychain Access?

Sometimes specific credential entries are hidden by the system or grouped differently. If you cannot find the exact entry, updating your Microsoft account password online will invalidate the hidden cached token and force the app to ask for fresh credentials.

Does this issue affect all Microsoft apps on macOS?

Yes, it commonly affects applications like Microsoft Excel, Word, To Do, and Teams that rely on shared Microsoft authentication frameworks. The solution of reloading apps and resetting the password generally applies across all these applications.
