    1. Follow [this](#configure-a-federated-credential-to-use-oidc-based-authentication) guidance to create a Federated Credential associated with your Azure Managed Identity or AD App (Service Principal). This is needed to establish OIDC trust between GitHub deployment workflows and the specific Azure resources scoped by the Managed Identity/service principal.
    2. In your GitHub workflow, Set `permissions:` with `id-token: write` at workflow level or job level based on whether the OIDC token needs to be auto-generated for all Jobs or a specific Job.
    3. Within the Job deploying to Azure, add Azure/login action and pass the `client-id` and `tenant-id` of the Azure Managed Identity/service principal associated with an OIDC Federated Identity Credential created in step (i). You also need to pass `subscription-id` or set `allow-no-subscriptions` to true.
-- To login using Managed Identities, follow [this](#configure-azure-managed-identities-with-self-hosted-runners) guidance.

-- The Action provides a parameter `auth-type` with value list `[SERVICE_PRINCIPAL, IDENTITY]` to identify the type of authentication.
-  1. If `auth-type: SERVICE_PRINCIPAL` with `clientId`, `tenantId` and `clientSecret` detected in your input, we will attempt to login by using service principal with the secret.
-  2. If `auth-type: SERVICE_PRINCIPAL` with `clientId` and `tenantId` detected in your input, we will attempt to login by using OIDC.
-  3. If `auth-type: IDENTITY` with `clientId` detected in your input, we will attempt to login by using user-assigned managed identity.
-  4. If `auth-type: IDENTITY` without `clientId` detected in your input, we will attempt to login by using system-assigned managed identity.
