Microsoft Entra ID

Microsoft Entra ID now offers secretless application registrations, enhancing security by eliminating the need for client secrets in OAuth flows.
Traditionally, developers registered applications in Entra ID and generated client secrets for authentication, which posed security risks if not managed properly.
The new approach allows applications to authenticate using user-assigned managed identities, removing the reliance on client secrets.
This method streamlines authentication processes and reduces potential vulnerabilities associated with secret management. Implementing secretless authentication involves creating a user-assigned managed identity, linking it to an app registration, and updating application code to utilize this identity for authentication.
It aligns with the broader movement towards passwordless and more secure authentication methods in application development.
