You can't create credentials for a Native application. The redirect URI is the endpoint to which the user is sent by the authorization server (Azure AD B2C, in this case) after completing its interaction with the user, and to which an access token or authorization code is sent upon successful authorization. At this time (End of July 2019), the app registration UX in Azure portal still block query parameters. To help prevent phishing attacks, the device code flow now includes a prompt that validates the user is signing into the app they expect. This tutorial shows you how to register a web application using the Azure portal. Protocol impacted: OAuth and OIDC flows that use response_type=query - this covers the authorization code flow in some cases, and the implicit flow.

Azure AD will no longer double-encode this parameter, allowing apps to correctly parse the result. These changes aren't expected to break any existing clients, and will ensure that requests sent to Azure AD are reliably handled every time. You can also use the platform for authorizing scoped, permissions-based access to your web API. The other response fields are intended for consumption only by humans troubleshooting their issues.

During development, it's common to also add the endpoint where you run your app locally, like https://127.0.0.1/auth-response or http://localhost/auth-response. The error scenario has been updated, so that during non-interactive authentication (where prompt=none is used to hide UX), the app will be instructed to perform interactive authentication using an interaction_required error response. If you're using a native app instead (e.g. If you choose not to use a certificate, you can create a new application secret. Security best practices for application properties - Microsoft Entra Before your applications can interact with Azure Active Directory B2C (Azure AD B2C), they must be registered in a tenant that you manage.

Application and service principal are used interchangeably, but an application is like a class object while a service principal is like an instance of the class. If your code runs on a service that supports managed identities and accesses resources that support Azure AD authentication, managed identities are a better option for you. Only misconfigured clients (those without token caching or those exhibiting prompt loops already) will be impacted by this error. These requests may or may not be successful, but they all contribute to poor user experience and heightened workloads for the IDP, increasing latency for all users and reducing availability of the IDP.
