Solution 1Recommended

Clear Credential Manager and Re-sign into iCloud

Clearing outdated or corrupted iCloud credentials from Windows is the most effective way to stop recurring password prompts.

Windows stores login information in the Credential Manager. When these credentials become corrupted or out of sync with Apple's servers, it triggers repeated password requests.

1
Open Windows Credential Manager

Press the Windows key, type 'Credential Manager' in the search bar, and select it from the results.

2
Remove Apple Credentials

Click on 'Windows Credentials', locate any saved entries related to iCloud or Apple, and click 'Remove'.

3
Sign Out of iCloud

Open the iCloud for Windows app, click 'Sign Out', and then restart your computer to clear temporary cache.

4
Sign Back In

After restarting, open iCloud for Windows and sign back in. Use an app-specific password if you have two-factor authentication enabled on your Apple ID.

App-Specific Passwords: If your Apple ID uses two-factor authentication, you must generate an app-specific password at appleid.apple.com to allow Windows to securely connect to iCloud.

Frequently Asked Questions

Why does Microsoft 365 keep asking for my iCloud password?

This usually happens when the saved login credentials in the Windows Credential Manager become corrupted, or when Apple's security protocols require an app-specific password for third-party integrations.

What is an app-specific password and how do I get one?

An app-specific password is a unique, one-time generated password that allows non-Apple apps to securely access iCloud. You can generate one by logging into appleid.apple.com, navigating to the App-Specific Passwords section, and selecting 'Generate Password'.

Will reinstalling Microsoft 365 fix the iCloud prompt issue?

No, reinstalling Microsoft 365 typically does not resolve this issue because the credentials and sync conflicts are managed by the iCloud for Windows app and the Windows Credential Manager.
