Clear Keychain Credentials and Reset Office License

Removing corrupted login tokens from the Mac Keychain and resetting the Office license state resolves most continuous authentication loops.

macOS updates can sometimes cause Microsoft Office authentication tokens saved in the Keychain to become desynchronized or corrupted. Clearing these outdated entries forces the application to generate fresh, working credentials.

1
Sign out and quit applications

Open Microsoft Word, sign out of your user account from the profile menu, and completely quit all Office applications including Word, Excel, and PowerPoint.

2
Clear Keychain Access entries

Open Finder, go to Applications > Utilities, and launch Keychain Access. Search for 'Office' and delete related password entries. Also search for and delete any 'ADAL' entries, which are used for authentication.

3
Run the license removal tool

Download and run the official Microsoft Office license-removal tool. Follow the on-screen prompts to clear the activation state from your Mac.

4
Restart and sign in

Restart your Mac to ensure all changes take effect. Open Microsoft Word and sign in again with your Microsoft email and password to reactivate your license.

Data Safety: Using the license removal tool and clearing Keychain entries will not delete your local or cloud documents. It only resets your login and activation status.

Frequently Asked Questions

Why does Word for Mac ask me to sign in every time I open an online file?

This usually occurs when the cached login credentials (tokens) in your Mac's Keychain become corrupted or out of sync, a common issue following major operating system updates like macOS Sonoma.

What are ADAL entries in Mac Keychain?

ADAL stands for Active Directory Authentication Library. These entries are digital tokens used by Microsoft Office to securely authenticate your account. Deleting them forces Office to require a fresh login and generate new tokens.

Will removing the Office license delete my saved documents?

No. The license removal tool only clears the activation data and sign-in state from the application's hidden system folders. Your personal documents, whether saved locally or in OneDrive, remain perfectly safe.

Can I edit my Word documents in the browser as a workaround?

Yes. As a temporary workaround, you can log in to Office for the Web to open and edit your shared documents in Safari or Chrome without triggering the desktop app's repeated sign-in prompt.
