Problem Description: Lost Old Device Which

Hi, I lost my old device which store mfa to access admin portal and i cant access admin portal now

Quick Answer for Office Setup on New Device

If you have lost your primary authentication device and cannot access the Microsoft 365 admin portal, verify whether any other administrators remain active in your tenant.

Likely Causes Behind MFA Root Factors

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

• Cached credentials, outdated builds, or damaged local components can trigger mfa & verification issues.

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

Recommended Solution: Fixing MFA Step by Step

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

1. If additional admins exist, immediately contact one of them to revoke your current multi-factor authentication sessions and force a re-registration through the Microsoft Entra admin center.

2. Navigate to the security settings within the admin portal, locate your user account, and select the option to manage authentication methods.

3. This will invalidate the lost device credentials and prompt you to set up a new authenticator app or phone number upon your next login.

4. For detailed navigation instructions, consult the official Microsoft Learn documentation on managing authentication methods for Microsoft Entra multifactor authentication.

5. Ensure that all critical backup authentication methods are updated after regaining access to prevent future lockouts.

Alternative Solutions for Secondary Login Fixes

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: 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.

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.

FAQs About Office Support Questions

Can WPS Office fix this mfa & verification issues issue directly? Only when the WPS steps match the formatting or file task. Account, activation, and cloud issues stay on the Microsoft side.

Should I reinstall Office before trying these steps? Not first. Confirm account, license, and the exact error before reinstalling.

What should I send to Microsoft Support? The affected account email, device type, Office version, exact error text, and screenshots with personal data hidden.
