Error AADSTS50076 while trying to acquire token to embedded Power BI using JS API

I developed a new feature in my web portal that embedded Power BI Reports and it works fine in my PC, in "development enviorament", but when I publish to "homolog enviorament", the function that acquires token doesnt work properly and returns the following error:

{"error":"interaction_required","error_description":"AADSTS50076: Due to a configuration change made by your administrator, or because you moved to a new location, you must use multi-factor authentication to access '00000009-0000-0000-c000-000000000000'. Trace ID: 81bf8680-6f0f-4a07-8859-54549ae00600 Correlation ID: c4c81d67-5401-4d62-80f7-e481bc4ccaf9 Timestamp: 2025-05-27 21:17:09Z","error_codes":[50076],"timestamp":"2025-05-27 21:17:09Z","trace_id":"81bf8680-6f0f-4a07-8859-54549ae00600","correlation_id":"c4c81d67-5401-4d62-80f7-e481bc4ccaf9","error_uri":"https://login.microsoftonline.com/error?code=50076","suberror":"basic_action"}

My request to acquireToken use the following structure:

POST https://login.microsoftonline.com/common/oauth2/token $scope=openid &resource=https://analysis.windows.net/powerbi/api &client_id={clientId} &username={email} &password={password} &grant_type=password &client_secret={clientSecret}

I have been use this method for many years and in 5 different web portal and works fine.
I already created an "app" in Azure, made the configuration, give a lot of API Permissions in "app", grant admin consent.
How can I manage this error? This is because I need to use multi factor authentication to login? How can I acquire token and still use MFA? (I'm think the guy from IT does not allow me to remove MFA from account)

Hi @gluizqueiroz,

Thank you for reaching out to the Microsoft Fabric Forum Community.

The error code AADSTS50076 typically indicates that Multi-Factor Authentication (MFA) is required due to a policy change or new sign-in location. This often occurs when using authentication flows that do not support MFA, such as the Resource Owner Password Credential (ROPC) grant.

To resolve this issue, please refer to the official Microsoft documentation here:

https://learn.microsoft.com/en-us/entra/identity-platform/reference-error-codes#aadsts50076

If this solution helped, please consider marking the response as accepted and giving it a thumbs-up so others can benefit as well.

Hello, Prasanna Kumar!
Thanks for the answer so far, but: How can I manage this error?

I need to check or uncheck something at Azure?
What I need to do to receive a token after request?
I need to disable MFA for the user?

Hi @gluizqueiroz

Thank you for reaching out to the Microsoft Fabric Forum Community.

You're using the ROPC flow, which doesn't support MFA, so it fails when your Azure AD enforces it.

To Fix without disabling MFA, Use MSAL.js with Authorization Code Flow (for user login) or Client Credentials Flow (for backend apps).
Both support MFA and comply with Azure AD policies.

Please refer for documentation.

Thanks for reply!

Interesting solutions and article about MSAL, I will study more about this in the future.
By now, I solved the problem releasing the MFA when the request comes from specific IPs adresses. My application is located in a specific and stable VM with static IP adress, so, every request to Azure, starts from the same IP adress, and only 1 IP, knowing this fact, I add the IP address at the following:

https://entra.microsoft.com/#view/Microsoft_AAD_AuthenticationMethods/MultifactorAuthenticationConfig.ReactView

And go to tab "Service config".

Thanks for replying and trying to help me.
