Problem Description: Problema Con Microsoft Authenticator

Me he cambiado de móvil ya que mi anterior móvil dejó de funcionar y ahí tenía el Microsoft authenticator instalado con la cuenta de mi universidad. Al intentar iniciar sesión en esta aplicación en el nuevo móvil me pide que use la misma aplicación para poner un número pero no puedo porque estoy intentando iniciar sesión. Necesito soluciones cuanto antes. Y no me puedes dar una solución para poder iniciar sesión sin que me pida el número de Microsoft authenticator --- *Movido desde: Seguridad de Microsoft | Microsoft Authenticator*

Quick Answer for Office Won't Complete Task

If you cannot access Microsoft Authenticator after switching devices, request that your organization's administrator reset your multifactor authentication settings to generate a new verification code or allow fresh registration on your new hardware.

Likely Causes Behind Common MFA Triggers

• 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• Cached credentials, outdated builds, or damaged local components can trigger mfa & verification issues.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: Installing Office on a New PC

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

1. Alternatively, attempt to sign in using any previously configured backup verification methods, such as an alternate phone number or secondary email address.

2. If these self-service options fail, contact your institution's technical support team immediately.

3. Provide them with your account details so they can execute specialized recovery procedures tailored to your educational environment's security policies and restore your authentication capabilities without compromising your organizational data.

Alternative Solutions for Broader MFA Workarounds

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: Using WPS While Office Is Unavailable

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 Avoiding Repeat MFA

• 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.
