Question details

The user is unable to reset their organization-managed Microsoft account password because the two-factor authentication verification codes are being sent to a phone number they no longer own.

Product: Microsoft 365
Device & OS: not provided
Scenario: Attempting to recover or reset a work or school account without access to the registered verification phone number.
Observed behavior: Verification codes are routed to an obsolete phone number, preventing the user from completing the password reset process.

Before you start

Check if you have previously set up any alternate verification methods, such as an alternative email address or the Microsoft Authenticator app, before attempting a complete reset.

Solution 1Recommended

Use the Microsoft Self-Service Password Reset Tool

If your organization has enabled the self-service password reset (SSPR) feature, you may be able to use an alternative authentication method to bypass the old phone number.

This method only works if your IT department has enabled self-service recovery and you have registered at least one secondary backup method (like a personal email or authenticator app).

Access the reset portal

Open your web browser and go to passwordreset.microsoftonline.com.

Enter your credentials

Type in your work or school email address, complete the CAPTCHA characters on the screen, and click 'Next'.

Select an alternate method

On the verification screen, choose a different contact method (e.g., 'Email my alternate email' or 'Approve a notification on my authenticator app') instead of the outdated phone number.

Reset password

Follow the on-screen prompts to verify your identity and create a new password.

Alternative Options Missing: If the outdated phone number is the only option presented, you do not have SSPR properly configured and must proceed to the next solution.

Solution 2

Contact Your Organization's IT Administrator

If self-service reset is unavailable, you must contact your company or school's IT support to regain access to your account.

Solution 3

Update Verification Phone Number (For Administrators)

If you are the account administrator, you can manually update the affected user's authentication phone number through the admin portal.

Frequently Asked Questions

Can I bypass the phone verification to log in to my work account?

No. For security and compliance reasons, if multi-factor authentication (MFA) is enforced by your organization, you cannot bypass it. You must either use an alternate approved verification method (like an authenticator app) or have an admin reset your MFA settings.

How long does it take for a phone number update by an admin to take effect?

Once an IT administrator updates your authentication contact details or clears your previous MFA sessions in the Microsoft 365 admin center, the changes typically take effect within a few minutes.

What if I am the only administrator and my phone number is outdated?

If you are the sole global administrator for your organization and are completely locked out, you will need to contact Microsoft Data Protection support directly. They will require you to provide specific evidence to verify your identity before restoring access, which can take several days.
