What is Microsoft Entra authentication?

Authentication is the process of verifying a person's identity before granting access to a resource, application, service, device, or network. It's how a system makes sure users are who they say they are when they try to sign in.

Authentication methods supported by Microsoft Entra ID

The following table outlines when an authentication method can be used for primary authentication (first factor), secondary authentication with Microsoft Entra multifactor authentication (MFA), and self-service password reset (SSPR).  

Method Primary authentication Secondary authentication
Windows Hello for Business Yes MFA1
Platform Credential for macOS Yes MFA
Passkey (FIDO2) Yes MFA
Passkey in Microsoft Authenticator Yes MFA
Synced passkey Yes MFA
Certificate-based authentication Yes MFA
Microsoft Authenticator passwordless Yes No
Microsoft Authenticator push notifications Yes MFA and SSPR
Authenticator Lite No MFA
Hardware OATH tokens (preview) No MFA and SSPR
Software OATH tokens No MFA and SSPR
External authentication methods (preview) No MFA
Temporary Access Pass (TAP) Yes MFA
Short Message Service (SMS) sign-in Yes MFA and SSPR
Voice call No MFA and SSPR
QR code Yes No
Email OTP No SSPR and sign-in2
Password Yes No

1Windows Hello for Business can serve as a step-up MFA credential if a user is enabled for passkey (FIDO2) and has a passkey registered.

2Email OTP is available for tenant members for self-service password reset (SSPR). You can also configure it for sign-in by guest users.

Phishing-resistant authentication methods  

While traditional MFA with SMS, email OTP, or authenticator apps significantly improves security over password-only systems, these options introduce friction—requiring additional steps for users, like entering codes, approving push notifications, or using authenticator apps. Moreover, these MFA options are prone to remote phishing attacks. In a remote phishing attack, attackers use social engineering and AI-driven tools to steal identity credentials—like passwords or one-time codes—without physical access to a user's device. 

Microsoft recommends using phishing-resistant authentication methods such as Windows Hello for Business, passkeys (FIDO2) and FIDO2 security keys, or certificate-based authentication (CBA) because they provide the most secure sign-in experience.

The following phishing-resistant authentication methods are available in Microsoft Entra ID. 

  • Windows Hello for Business
  • Platform Credential for macOS
  • Synced passkeys (FIDO2)
  • FIDO2 security keys
  • Passkeys in Microsoft Authenticator
  • Certificate-based authentication (CBA) 

High-assurance account recovery

Account recovery is the process of helping users who lost all their credentials and can no longer access their account. Traditionally, a user calls the help desk, answers questions to verify their identity, and the help desk resets their credentials. Microsoft Entra ID now supports government-issued ID verification with AI-powered biometric matching for high-assurance account recovery.

Organizations can choose from the leading identity verification providers (IDV) through the Microsoft Security Store: Idemia, Lexis Nexis, and Au10tix. These partners offer coverage across 192 countries/regions and remote verification for most government-issued ID documents, including driver's licenses and passports. Microsoft Entra Verified ID Face Check, powered by Azure AI services, adds a critical layer of trust by matching a user’s real-time selfie to the photo from their identity document. By sharing only the match results and not any sensitive identity data, Face Check improves user privacy while allowing enterprises to verify that the person claiming an identity is who they claim to be.

Once enabled, this capability provides a natively integrated end-to-end flow for users to securely regain access to their accounts. For more information, see Overview of Microsoft Entra ID account recovery.
