Key Features: Single Sign-On, Multi-Factor Authentication, and Self-Service Password Reset
Introduction
- Identity security is a critical part of IT infrastructure, ensuring that only authorized users access applications and services securely.
- Microsoft Entra ID (formerly known as Azure Active Directory or Azure AD) is Microsoft’s cloud-based identity and access management (IAM) service.
- It provides three essential features that improve security and user experience:
- Single Sign-On (SSO) – Enables users to log in once and access multiple applications seamlessly.
- Multi-Factor Authentication (MFA) – Strengthens security by requiring an additional verification step beyond passwords.
- Self-Service Password Reset (SSPR) – Allows users to reset their passwords securely without IT support.
- These features help reduce cybersecurity risks, prevent unauthorized access, and simplify authentication processes.
1. What is Single Sign-On (SSO)?
✔ Single Sign-On (SSO) is a feature that allows users to authenticate once and access multiple applications without logging in again.
✔ It reduces password fatigue by allowing users to remember and use only one set of credentials.
✔ Microsoft Entra ID (Azure AD) enables SSO for cloud and on-premises applications, including Microsoft 365, third-party SaaS applications, and custom apps.
How SSO Works
- User logs in using Microsoft Entra ID credentials.
- Microsoft Entra ID authenticates the user and issues a security token.
- The token grants access to multiple integrated applications without additional login prompts.
Benefits of SSO
✔ Improves User Experience – Reduces the need to enter passwords multiple times.
✔ Enhances Security – Reduces the risk of password-related attacks.
✔ Minimizes IT Support Requests – Reduces password reset requests.
✔ Simplifies Access Management – Centralizes authentication across applications.
2. What is Multi-Factor Authentication (MFA)?
✔ Multi-Factor Authentication (MFA) is an additional security layer that requires users to verify their identity using multiple factors.
✔ Microsoft Entra ID (Azure AD) supports MFA to prevent unauthorized access, even if a user’s password is stolen.
How MFA Works
- User enters their Microsoft Entra ID credentials (username and password).
- A second verification step is required, such as:
- One-time passcode (OTP) sent via SMS or email.
- Approval via Microsoft Authenticator app.
- Biometric authentication (fingerprint or facial recognition).
- If both authentication factors are verified, the user gains access.
Benefits of MFA
✔ Prevents Unauthorized Access – Protects accounts from phishing and credential theft.
✔ Supports Multiple Authentication Methods – Allows SMS, email, authenticator apps, and biometrics.
✔ Meets Compliance Requirements – Ensures compliance with industry standards like ISO, GDPR, and PCI-DSS.
✔ Reduces Security Risks – Even if a password is compromised, attackers cannot access accounts without the second factor.
3. What is Self-Service Password Reset (SSPR)?
✔ Self-Service Password Reset (SSPR) allows users to reset their passwords securely without needing IT support.
✔ Microsoft Entra ID (Azure AD) provides SSPR as a secure way to handle password recovery.
How SSPR Works
- User forgets their password and clicks “Forgot Password” on the login screen.
- Microsoft Entra ID prompts the user to verify their identity using one or more authentication methods (e.g., OTP via email or phone).
- Once verified, the user can create a new password and regain access.
Benefits of SSPR
✔ Reduces IT Workload – Eliminates helpdesk requests for password resets.
✔ Enhances Security – Ensures users go through secure identity verification.
✔ Improves User Productivity – Users can reset passwords anytime without waiting for IT support.
✔ Supports Conditional Policies – Administrators can enforce security policies for password resets.
4. How These Features Work Together in Microsoft Entra ID (Azure AD)
✔ Single Sign-On (SSO) simplifies user access by allowing login to multiple applications using one set of credentials.
✔ Multi-Factor Authentication (MFA) strengthens security by adding an extra layer of authentication to prevent unauthorized access.
✔ Self-Service Password Reset (SSPR) enhances user convenience by enabling users to reset their own passwords securely.
Example Scenario
- A user logs in to Microsoft 365 using SSO.
- Microsoft Entra ID checks if the user needs to complete MFA for security verification.
- If the user forgets their password, they can reset it using SSPR without contacting IT.
5. Benefits of Using These Features
✔ Stronger Security – Protects against identity theft, phishing, and unauthorized access.
✔ Improved User Experience – Users can access applications easily without multiple logins.
✔ Reduced IT Costs – Fewer helpdesk calls for password resets and account recovery.
✔ Meets Compliance Requirements – Helps organizations comply with security standards like ISO, GDPR, and NIST.
6. Use Cases of SSO, MFA, and SSPR
✔ Enterprise IT Security – Ensures secure authentication across corporate applications.
✔ Remote Work Security – Protects VPN and cloud access for remote employees.
✔ SaaS Application Access – Enables secure access to third-party applications like Salesforce and Dropbox.
✔ Education Sector – Allows students and faculty to access learning platforms securely.

Answers and Explanations
- B – Allow users to access multiple applications with one login
- ✅ Correct: SSO lets users log in once and access multiple applications without re-entering credentials.
- ❌ Wrong: SSO does not encrypt passwords, store credentials, or improve database performance.
- A – Requires additional verification beyond passwords
- ✅ Correct: MFA strengthens security by requiring a second factor (OTP, biometrics, or authenticator apps).
- ❌ Wrong: It does not block all logins, reset passwords automatically, or affect storage costs.
- A – Allow users to reset passwords without IT help
- ✅ Correct: SSPR reduces IT workload by allowing users to reset passwords securely.
- ❌ Wrong: It does not block logins, encrypt credentials, or improve speed.
- C – Username and password only
- ✅ Correct: MFA requires more than just a password, such as OTPs or biometric verification.
- ❌ Wrong: OTP, fingerprint, push notifications, and authenticator apps are valid MFA methods.
- D – All of the above
- ✅ Correct: SSO improves security, eliminates password fatigue, and enhances productivity.
- ❌ Wrong: None of the other options provide all these benefits alone.
