Hi @slim gharbi

Could you clarify what you mean by “Pro” account? Do you mean a work or school account?

The recovery steps are different depending on whether the account is personal or work or school.

1.For work or school account (@domain.com or @onmicrosoft.com)

Please contact your organization's IT administrator and ask them to reset your authentication method so that you can register Microsoft Authenticator again. The administrator can follow Microsoft's documentation here: Manage authentication methods for Microsoft Entra multifactor authentication - Microsoft Entra ID |… 

If you're unsure who your IT administrator is, please refer to How do I find my Microsoft 365 admin? - Microsoft Support 

2.For personal Microsoft account (@outlook.com, @hotmail.com, @live.com), you can try one of the following options: 

-Use the Microsoft Account Recovery Form: Help with the Microsoft account recovery form | Microsoft Support 

-Alternatively, contact Microsoft Support: Go to Contact - Microsoft Support, > type "Support" and click Get Help, > click Sign in to contact support at the bottom of the > page under Products & Services, select Microsoft 365 & Office > under Subcategory, select Support, > choose Chat with a support agent in your browser.

If you cannot use any of the available verification methods, Microsoft Support will be in the best position to determine what account-recovery options are available.

I hope this helps clarify the appropriate recovery path depending on whether the account is personal or managed by an organization.
