Word FAQs About Microsoft 365 Verification Loop on MacOS After Password Reset

Why does Excel for Mac ask for verification even after I receive a password change confirmation?

This happens because Microsoft Office apps on MacOS rely on the built-in "Keychain Access" to store login tokens. Your browser updated the password on Microsoft's servers, but the old token is still stuck in your Mac's Keychain. You must manually delete the old token in Keychain for Excel to recognize the new password.

Will deleting Microsoft entries in Keychain Access delete my Excel files?

No. Keychain Access only stores passwords and authentication tokens, not your personal documents. Deleting the "Microsoft Office Credentials" simply forces the application to ask you for your login details again on the next launch. Your local .xlsx files and OneDrive cloud files remain completely safe.

What should I do if the verification prompt keeps flashing and disappearing quickly?

A flashing login prompt usually indicates a conflict with the Microsoft AutoUpdate tool or corrupted ADAL (Active Directory Authentication Library) tokens. Close Excel completely, open Keychain Access, search for both ADAL and Office, delete all related Microsoft items, and then restart your Mac before opening Excel again.

How can I edit my Excel files immediately if Microsoft 365 remains locked?

If you are still stuck in a verification loop and need urgent access to your spreadsheets, you can download WPS Office for Mac. It is a highly compatible, free alternative that opens .xlsx files locally without requiring a Microsoft 365 subscription or dealing with Microsoft account verification steps.
