Hi @able-thailand-87943, in the Azure Native provider, both are supported. The config keys/env variables for cert auth are
• `clientCertificatePath`/`ARM_CLIENT_CERTIFICATE_PATH`
• `clientCertificatePassword`/`ARM_CLIENT_CERTIFICATE_PASSWORD` (optional)
• for the id, `clientId`/`ARM_CLIENT_ID` and `tenantId`/`ARM_TENANT_ID`
