Fix Microsoft Authenticator Not Receiving Codes for Partner Directory
Question details
The user is unable to receive multi-factor authentication (MFA) codes when attempting to switch to a partner organization directory in the Azure portal.

- Product
- Microsoft Authenticator / Azure Active Directory
- Device & OS
- not provided
- Scenario
- Accessing a partner directory (B2B guest access) in the Azure portal that requires multi-factor authentication.
- Observed behavior
- Microsoft Authenticator codes are successfully received for the primary organization account but do not arrive for the partner organization directory.
Ensure you have a stable internet connection and that the Microsoft Authenticator app is updated to the latest version on your mobile device.
Request an Authentication Method Reset from the Partner Admin
If you are using a work or school account as a guest in a partner directory, the admin of that specific directory must reset your MFA methods.
Because you are accessing a partner directory, your primary organization's admin cannot fix this issue. The partner organization independently manages your guest account's authentication settings in their tenant.
Reach out to the IT administrator or helpdesk of the partner organization you are trying to access.
Ask them to navigate to their Azure portal, locate your guest account in their Azure Active Directory, and select 'Authentication methods'.
Instruct the admin to click the 'Require re-register MFA' option for your guest profile.
Log in to the partner directory once more. You will be prompted to set up the Microsoft Authenticator app from scratch for that specific directory.

Contact Microsoft Support for Locked-Out Administrators
Use this method if you are the only global administrator for the directory and are completely locked out due to the MFA issue.

Frequently Asked Questions
Why do Authenticator codes work for my main account but not the partner directory?
Partner directories treat you as a guest user. Your multi-factor authentication (MFA) settings are tied specifically to the partner's Azure AD tenant, which is completely independent of your primary organization's setup. If the guest MFA token breaks, codes will stop arriving for that specific directory.
Can my primary organization's IT department fix this MFA issue?
No. Your primary IT department does not have administrative rights over the partner organization's directory. You must contact the partner organization's IT support to reset your MFA methods.
What if I am using a personal Microsoft account for the partner directory?
If you are using a personal Microsoft account to access a business partner directory, you are still considered a guest. You must ask the partner organization's administrator to reset your guest account MFA in their Azure portal.
