Why Word Keeps Security Prompt Problem and How to Fix It

This guide walks you through sign-in & login problems using Microsoft-supported steps first, with WPS only where it genuinely helps.

Problem Description: Windows Security Prompt Problem

I get a recurring Office authentication loop "Windows Security" requesting the password for an email I no longer use. It appears every time I open any office app. I had a remote session with a Microsoft technician on January 12. At first it looked like the problem was solved, but after a few hours it returned. I need remote help again to solve it. My case number is 7095755131

Quick Answer for Sign-in Quick Fix

Remove stored credentials by going to Control Panel > User Accounts > Credential Manager > Manage Windows Credentials, and delete entries related to the email account prompting for a password.

Likely Causes Behind Office Failure Patterns

• The Microsoft account or license context may not match the purchase or device.

• Cached credentials, outdated builds, or damaged local components can trigger sign-in & login problems.

• A file-specific corruption or add-in conflict can mimic a broader application failure.

Recommended Solution: Repairing Office Startup Issues

When to use this: Apply these steps when the symptoms match and you can access the relevant Microsoft account or administrator.

1. Restart Outlook and re-enter credentials when prompted.

2. If the issue persists, create a new Outlook profile via Control Panel > Mail > Show Profiles.

3. Enable Modern Authentication if supported by your organization to prevent repeated prompts.

Alternative Solutions for Fallback Options for Sign-in

1. Retry the Microsoft-side steps after restarting the app and device.

2. Test the same action in a private browser session or a new blank file to isolate account vs file issues.

3. Capture exact error text and screenshots before contacting Microsoft Support or your administrator.

Working with WPS Office: Editing Files in WPS During Sign-in

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.

1. Download and install WPS Office from the official website.

2. Open local Word, Excel, PowerPoint, or PDF files in the matching WPS app.

3. Save a working copy locally while Microsoft-side issues are resolved.

4. 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 Smooth Office Device Transfers

• 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.
