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:
- Microsoft Entra ID Premium P1 or P2 license for each user who will use password writeback
- Azure AD Connect is installed and configured
- On-premises Active Directory (Windows Server 2012 or newer)
- Network connectivity between the Azure AD Connect server and your Domain Controllers
- 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:
- Download the latest Azure AD Connect installer from the Microsoft portal
- Run the installer and select Customize instead of Express settings
- Proceed through the configuration until you reach the Optional Features screen
- Check the box for Password writeback
- 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:
- Open the Azure AD Connect configuration wizard
- Select Customize synchronization options
- Enter your Microsoft Entra ID credentials
- Navigate to Optional Features
- Check the box for Password writeback
- 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
- Sign in to the Microsoft Entra admin center
- Navigate to Protection > Password reset
- Under On-premises integration
