Tutorial / Cram Notes
Here, we’ll delve into the features and capabilities that Azure AD offers to help organizations bolster their security posture in terms of password management.
Default and Custom Password Protection Policies
Azure AD provides robust password protection policies designed to deter attackers from guessing or cracking user passwords. These policies include password complexity requirements and are enabled by default. They enforce rules such as:
- Minimum password length
- Restriction on password reuse
- Banning of common passwords
- Password expiration policies
Custom password policy settings also exist where administrators can tailor the policies for their organizations. For example, an admin might specify password expiry after a certain number of days or sign-in attempts.
Multi-Factor Authentication (MFA)
Azure AD supports Multi-Factor Authentication (MFA), adding an extra layer of security by requiring two or more verification methods. This might include:
- Something you know (password or pin)
- Something you have (phone or hardware token)
- Something you are (fingerprint or other biometric)
Integrating MFA dramatically reduces the chances of unauthorized access, even if a password has been compromised.
Self-Service Password Reset (SSPR)
Azure AD has a Self-Service Password Reset feature that enables users to change or reset their passwords without administrator intervention. This capability is beneficial for both user experience and reducing the burden on IT support. SSPR can be combined with Azure AD Identity Protection to create risk-based policies that require users to reset their password if suspicious activity is detected.
Azure AD Identity Protection
Azure AD Identity Protection leverages machine learning to detect and mitigate potential risks such as atypical user behavior and known compromised credentials. With risk-based conditional access policies, organizations can automatically respond to detected issues, such as forcing a password reset or requiring MFA.
Azure AD Password Protection
Azure AD Password Protection prevents users from creating weak or commonly used passwords. It maintains a global banned password list that’s updated based on analyses of attacks. Organizations can also maintain a custom list of additional words that users are prohibited from using in passwords.
Privileged Identity Management (PIM)
Azure AD also includes Privileged Identity Management, which adds protection for privileged accounts through just-in-time privileged access to Azure AD and Azure resources. It sets a time-bound activation for administrative roles, reducing the time these elevated privileges can be exploited by an attacker if compromised.
Credential Management with Azure AD B2C
For scenarios that involve external users, such as customers or partners, Azure AD B2C (Business to Consumer) allows for the secure handling of their identities. It provides features like social identity provider integration, custom user attributes, and fine-grained password policies.
Comparison Table of Features
| Feature | Description | Benefit |
|---|---|---|
| Default Password Policy | Enforces standard complexity requirements across all accounts in the Azure AD directory. | Increases basic password security and reduces the likelihood of brute-force attacks. |
| Custom Password Policy | Allows adjustment of password policies to meet specific organizational needs. | Tailors password policies to the risk profile and regulatory requirements of the organization. |
| Multi-Factor Authentication | Requires one or more additional forms of verification beyond the password. | Significantly improves account security by adding additional verification steps. |
| Self-Service Password Reset | Enables users to reset their passwords without admin intervention. | Decreases the workload on IT support while enhancing the user experience. |
| Azure AD Identity Protection | Uses machine learning to detect suspicious activities and enforce conditional access policies. | Proactively protects against identity-based threats and compromised credentials. |
| Azure AD Password Protection | Prohibits the use of weak or common passwords through global and custom banned password lists. | Prevents users from choosing easily guessable passwords, enhancing security. |
| Privileged Identity Management | Manages, controls, and monitors access within Azure AD for privileged roles. | Minimizes the attack surface by reducing the amount of time accounts have elevated privileges. |
| Azure AD B2C Credential Management | Manages customer, partner, and consumer identities with custom policies and features. | Provides a scalable and secure solution for managing identities outside of the organization. |
Azure AD’s comprehensive password protection and management capabilities address a wide range of security concerns. The integration of these features allows organizations to significantly enhance their security posture in a cloud-centric environment, ensuring both user convenience and robust protection against potential security threats.

Interview Questions
What is Azure AD password protection?
Azure AD password protection is a feature that prevents the use of easily guessed passwords and ensures that users choose strong passwords that meet complexity requirements.
How does Azure AD password protection work?
Azure AD password protection works by comparing new passwords against a list of commonly used, predictable, and compromised passwords. If a user tries to use a password that is on the list, they will be prompted to choose a different password.
What is the banned password list in Azure AD password protection?
The banned password list is a list of commonly used, predictable, and compromised passwords that Azure AD password protection checks against when users create new passwords.
Can the banned password list be customized in Azure AD password protection?
Yes, the banned password list can be customized in Azure AD password protection to include additional words, phrases, or character strings that are specific to an organization.
What is the benefit of using Azure AD password protection?
The benefit of using Azure AD password protection is that it helps to protect against password-based attacks and ensures that users choose strong passwords that meet complexity requirements.
What is Azure AD password protection on-premises?
Azure AD password protection on-premises is a feature that extends Azure AD password protection to on-premises Active Directory environments.
How does Azure AD password protection on-premises work?

What is the benefit of using self-service password reset?
The benefit of using self-service password reset is that it reduces the workload on IT support and enables users to reset their passwords quickly and easily.
What is the difference between self-service password reset and password writeback?
Self-service password reset is a feature that allows users to reset their own passwords, while password writeback is a feature that allows password changes made in Azure AD to be written back to an on-premises Active Directory environment.
Can self-service password reset be configured to use multi-factor authentication?
Yes, self-service password reset can be configured to use multi-factor authentication to ensure that users verify their identity using more than one method.
What is password protection in Azure AD?
