Microsoft Entra Authentication Methods for Azure SQL Database
Which THREE are valid methods to authenticate to Azure SQL Database using Microsoft Entra ID?
Quick Answer
The three valid methods to authenticate to Azure SQL Database using Microsoft Entra ID are service principal authentication, Entra ID password authentication, and managed identity authentication. Service principal authentication allows an application or automation tool to authenticate via a client ID and secret or certificate, representing a non-human identity in Entra ID. Entra ID password authentication lets users sign in directly with their cloud credentials using an access token flow, ideal for contained database users. Managed identity authentication enables Azure resources like VMs or Functions to securely connect without storing secrets, using a system- or user-assigned identity. On the DP-300 exam, this topic tests your ability to choose cloud-native authentication for different scenarios—common traps include confusing integrated Windows authentication (which requires domain join) or overlooking managed identity for serverless workloads. Remember the mnemonic “SPM” for Service principal, Password, Managed identity—the three core Entra ID methods for Azure SQL.
⚠ Common exam trap
Many exam-takers confuse authentication methods with authentication tools or prerequisites, mistakenly thinking that a managed identity can authenticate without a contained database user or that Azure CLI is a direct authentication method for SQL Database rather than a token acquisition tool.

Correct answer & explanation
✓
Microsoft Entra ID password authentication
Microsoft Entra ID password authentication allows users to authenticate to Azure SQL Database using their Entra ID credentials directly, without requiring Windows domain join or integrated authentication. This method uses the Entra ID access token flow, where the user provides their username and password to obtain a token from the Microsoft Entra ID endpoint, which is then used to connect to the database. It is a straightforward, cloud-native authentication method supported for contained database users mapped to Entra ID identities.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
User-assigned managed identity without a contained database user
Why it's wrong here
A contained database user must exist for the managed identity.
- ✓
Microsoft Entra ID password authentication
Why this is correct
Supports username/password authentication via Entra ID.
- ✓
Integrated Windows authentication (Kerberos)
Why this is correct
Supported when domain is federated with Entra ID.
- ✗
Azure CLI authentication
Why it's wrong here
Azure CLI is for Azure management, not direct SQL authentication.
- ✓
Service principal authentication
Why this is correct
Applications can authenticate using service principals.

Same concept, more angles
3 more ways this is tested on DP-300
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. You are configuring authentication for Azure SQL Database. Which TWO of the following are supported authentication methods?
easy- A.Windows authentication using Kerberos.
- ✓ B.Microsoft Entra ID authentication with a service principal.
- C.OAuth 2.0 token authentication.
- ✓ D.SQL authentication with a username and password.
- E.Certificate-based authentication for SQL logins.
Why B: Microsoft Entra ID authentication with a service principal is supported in Azure SQL Database. A service principal is an identity created for use with applications, hosted services, and automated tools to access Azure resources, and it can authenticate to Azure SQL Database using Microsoft Entra ID (formerly Azure AD) tokens. This method enables secure, non-interactive authentication for applications and automation scenarios.
Variation 2. You need to configure authentication for Azure SQL Database. Which TWO options are supported?
medium- A.Multi-factor authentication
- B.Certificate-based authentication
- ✓ C.Azure Active Directory authentication
- ✓ D.SQL authentication
- E.Windows authentication
Why C: Azure SQL Database supports Azure Active Directory (Azure AD) authentication, which allows you to centrally manage identities and access. This includes support for modern authentication protocols like OAuth 2.0 and integration with Azure AD, enabling features such as conditional access and managed identities.
Variation 3. You are designing a secure environment for Azure SQL Database. Which authentication method provides the strongest security and supports multi-factor authentication?
easy- A.Certificate-based authentication
- ✓ B.Azure Active Directory authentication
- C.SQL authentication with strong passwords
- D.Windows authentication
Why B: Azure Active Directory (Azure AD) authentication is the recommended method for Azure SQL Database because it supports multi-factor authentication (MFA), conditional access policies, and identity-driven security. It eliminates the need for password management and leverages Azure AD's built-in security features, providing the strongest security posture for cloud-native environments.
