Azure Password Writeback

Azure Password Writeback is an invaluable feature for creating a seamless password management experience. This fills the gap between Microsoft Entra ID (formerly Azure AD) and your on-premises Active Directory environment. In this article, we will discuss what is password writeback, its features, and how to enable password writeback in Azure AD, etc.

Azure Password Writeback

What is Azure Password Writeback?

Azure Password Writeback is a feature that enables password changes made in the cloud to synchronize back to your on-premises Active Directory. This bi-directional synchronization creates a unified password experience for users regardless of where they’re working from.

When users reset or change their passwords through Microsoft Entra ID’s self-service password reset (SSPR) portal, those changes automatically propagate to your on-premises directory. This eliminates the traditional disconnect between cloud and on-premises credentials.

Why Password Writeback Matters for Your Organization

• Reduced IT Support Costs: Password reset requests account for approximately 20-50% of all helpdesk calls. Self-service options dramatically reduce this burden.
• Enhanced Security Posture: Enforce consistent password policies across environments.
• Improved User Experience: Users remember only one password, regardless of where they’re accessing resources from.
• Business Continuity: Users can reset passwords even when VPN connections are down.

Features of password writeback in Azure AD

Let’s discuss a few key features of Azure AD password writeback.

No-delay Response

While trying to change the password, if it doesn’t meet the password policy or for some reason you are unable to update your password, the writeback feature provides an immediate notification with a detailed explanation.

No inbound firewall rules are needed.

You don’t need any inbound firewall rule in case of Password writeback, as all communication is outbound over port 443.

Ensures your password meets your on-premises AD DS policy

Once you are trying to reset your password, this feature ensures that the password you enter meets your on-premises AD DS policy in terms of complexity, age, history, and restrictions.

Prerequisites for Implementation

Before diving into implementation, ensure your environment meets these requirements:

1. Microsoft Entra ID Premium P1 or P2 license for each user who will use password writeback
2. Azure AD Connect is installed and configured
3. On-premises Active Directory (Windows Server 2012 or newer)
4. Network connectivity between the Azure AD Connect server and your Domain Controllers
5. Proper permissions for the Azure AD Connect account

Implementation Methods

Let’s explore the two primary approaches for enabling this functionality

Approach 1: Enabling Password Writeback During Azure AD Connect Installation

This is the simplest approach if you’re setting up Azure AD Connect for the first time:

1. Download the latest Azure AD Connect installer from the Microsoft portal
2. Run the installer and select Customize instead of Express settings
3. Proceed through the configuration until you reach the Optional Features screen
4. Check the box for Password writeback
5. Complete the remaining configuration steps

Approach 2: Enabling Password Writeback on an Existing Azure AD Connect Installation

If you already have Azure AD Connect running, follow these steps to configure password writeback:

1. Open the Azure AD Connect configuration wizard
2. Select Customize synchronization options
3. Enter your Microsoft Entra ID credentials
4. Navigate to Optional Features
5. Check the box for Password writeback
6. Click Next and complete the configuration

Configuring Self-Service Password Reset with Writeback

Password writeback works in conjunction with Microsoft Entra ID’s self-service password reset capability. Here’s how to configure both:

Step 1: Enable Password Writeback in the Microsoft Entra Admin Center

1. Sign in to the Microsoft Entra admin center
2. Navigate to Protection > Password reset
3. Under On-premises integration, set Write back passwords to your on-premises directory to Yes
4. Save your changes. Please refer to the screenshot below for your reference.

Step 2: Configure Authentication Methods

For a robust implementation, I recommend requiring at least two authentication methods:

1. In the Microsoft Entra admin center, navigate to Protection > Password reset > Authentication methods
2. Select which methods to enable (phone, email, security questions, authenticator app)
3. Set the Number of methods required to reset to at least 2
4. Save your changes

Step 3: Define User Registration Policy

1. Navigate to Protection > Password reset > Registration
2. Decide whether to require users to register when signing in
3. Set the number of days before users must reconfirm their authentication information
4. Save your changes. Refer to the screenshot below for your reference.

Step 4: Define Password Reset Policy

1. Navigate to Protection > Password reset > Properties
2. Choose which users get self-service password reset capability:
   • None
   • Selected (choose specific groups)
   • All
3. Save your changes. Refer to the screenshot below.

Common Password Writeback Issues

In my years implementing this technology, I’ve encountered several common issues:

Issue 1: Password Changes Not Synchronizing to On-Premises AD

Possible causes and solutions:

Issue 2: “Something went wrong” Error During Password Reset

This generic error typically indicates that the password reset operation reached Azure AD but failed when writing back to the on-premises AD.

Troubleshooting steps:

1. Check the Event Viewer on your Azure AD Connect server
2. Review the Application and Services Logs > Microsoft > AzureADConnect > AdminUI
3. Look for error codes related to password writeback

Issue 3: Users Not Seeing the “Forgot Password” Option

Common solutions:

1. Verify the user is licensed for Microsoft Entra ID Premium P1/P2
2. Confirm the user is included in your password reset policy
3. Check that the user has registered their authentication methods

Best Practices

Based on my experience with numerous deployments, I recommend these best practices:

1. Start with a pilot group before rolling out to all users
2. Train your helpdesk staff on the new password reset workflow
3. Communicate clearly with users about the self-service options
4. Create custom documentation with screenshots specific to your environment
5. Enable notification emails for password resets to alert users
6. Regularly review audit logs for suspicious reset patterns

Integration with Other Microsoft Entra ID Features

Password writeback becomes even more powerful when combined with these complementary features:

Combined Registration Experience

Microsoft’s combined registration allows users to register for both SSPR and multi-factor authentication (MFA) in a single experience, improving adoption rates.

Password Protection

Implement Microsoft Entra ID Password Protection to prevent users from selecting commonly targeted passwords, thereby further enhancing your security posture.

Conditional Access Policies

Create policies that require stronger authentication when password changes come from risky locations or devices.

FAQs

How long does password writeback take to work

Answer: Under 500 ms.

How to check if password writeback is enabled

Answer: Run the Get-ADSyncAADCompanyFeature PowerShell command.

What types of accounts does password writeback work for

Answer: Synced IDs

Conclusion

As organizations continue their digital transformation journeys, technologies like password writeback fill the gap between on-premises systems and modern cloud services. By implementing this capability, you provide users with a seamless experience while maintaining security and reducing IT operational costs.

Password writeback is an excellent feature that helps when you change your password for your Azure AD in the cloud, automatically writing back the password to your existing on-premises directory.
