This guide walks you through mfa & verification issues using Microsoft-supported steps first, with WPS only where it genuinely helps.
Problem Description: Admin Account Having Trouble
Dear Support Team, We would like to inform you that the Admin account is currently facing an issue accessing the account due to a change in the registered mobile number. As a result, the account holder is unable to complete the verification process and cannot contact you directly. Accordingly, I am contacting you on their behalf to assist with resolving this issue. We kindly request your support in restoring access to the account or updating the verification details. Please note that I am fully prepared to provide any required personal information or account-related details needed for verification, in accordance with your procedures. Thank you for your cooperation and support. --- *Moved from: Microsoft Security | Microsoft Authenticator*

Alternative Solutions for Secondary Login Fixes

Test the same action in a private browser session or a new blank file to isolate account vs file issues.
Capture exact error text and screenshots before contacting Microsoft Support or your administrator.
Working with WPS Office: WPS as a Local Alternative

WPS Office cannot replace Microsoft account, activation, or cloud fixes for this scenario. It remains one of the best free Microsoft Office-compatible alternatives for opening and editing local files.
Download and install WPS Office from the official website.
Open local Word, Excel, PowerPoint, or PDF files in the matching WPS app.
Save a working copy locally while Microsoft-side issues are resolved.
Return to Microsoft Office after the primary fix succeeds.
If you need a practical local workspace in the meantime, try WPS Office.
Prevention Tips for Keeping Office Stable Long Term
Keep one primary Microsoft account for subscriptions and Office sign-in.
Install updates for Office and Windows before retrying failed workflows.
Back up important files before repair, reset, or reinstall actions.
Register more than one MFA method and keep recovery contacts current.
