Hello @Patrick Berkvens,

Thank you for connecting offline.

As we have discussed on call, I see you have changed the mobile phone and have forgotten to change the authenticator app to new phone and after that you were unable to login into Azure Portal due to not registered in new mobile phone.

As you are the only global admin on the account and are blocked entirely, you can reach out to our support team. You can look into below article to get support numbers depending on your country.

https://support.microsoft.com/en-us/topic/global-customer-service-phone-numbers-c0389ade-5640-e588-8b0e-28de8afeb3f2

or creating a ticket through a different account:  https://learn.microsoft.com/en-us/microsoft-365/admin/get-help-support?view=o365-worldwide#phone-support

Create a ticket with Microsoft support team. Give them the tenant ID which is locked out in your description. Tell them that no admin account has access anymore and your partners also have no access anymore.

Once you create a ticket with support team you will have to work with our data protection team. You will have to first prove your identity against your tenant for security purpose. Post that this team will help you with help you in getting access to your tenant or unlock your account depending on your scenario.

Also, for the future, you can create an emergency access account (break glass) in Azure AD. This account will help prevent being accidentally locked out of your Azure Active Directory (Azure AD) organization because you can't sign in for any reason.

Hello,

Welcome to Microsoft Q&A,

1. Visit the Microsoft 365 login page: https://login.microsoftonline.com/.
2. Click "Can't access your account?" or "Forgot password?".
3. Follow the instructions to reset your password or verify your identity

(or)

Ask the global administrator of the organization to reset your MFA settings and allow you to set up your new mobile phone and delete the old device.
