Entra.Chat

March 2026 is shaping up to be one of the most important months for Microsoft Entra ID administrators in recent memory.
Microsoft is automatically enabling passkey profiles in Entra ID, and if you don’t configure them yourself, your tenant will be migrated with default settings.
In this episode of Entra Chat, I sat down with Microsoft Security MVPs Daniel Bradley and Ewelina Paskowska to break down what this really means for Microsoft 365 administrators.
But passkeys aren’t the only story this month.
1️⃣ Passkey Profiles Are Becoming the Default
Starting March 2026:
* Passkey profiles will be auto-enabled
* Tenants that haven’t configured profiles will be migrated
* Registration campaigns will shift from Authenticator-first to passkey-first
This is a major shift toward phishing-resistant authentication.
You’ll now be able to:
* Separate hardware-backed vs synced passkeys
* Apply granular group-based controls
* Enforce stronger authentication for privileged users
2️⃣ Source of Authority Conversion Is Finally GA
For years, admins used messy delete-and-restore hacks to convert synced users to cloud-only.
Now it’s officially supported.
You can convert individual users from on-premises authority to cloud-managed — without breaking hybrid entirely.
Why this matters:
* Easier M&A transitions
* Full access to Entra ID Governance features
* Cleaner lifecycle management
* Reduced dependency on legacy infrastructure
For hybrid environments moving toward cloud-first identity, this is huge.

If you are a systems administrator managing endpoints every day, you’ve probably postponed patching at least once — not because you forgot… But because you didn’t feel like gambling with uptime. Meanwhile, the backlog grows, vulnerabilities pile up, and patching stays stuck in manual mode.
Action1  fixes that.
Action1 is a cloud-native patch management platform for Windows, macOS, Linux, and third-party apps — all from one place, no VPN needed. Curious how easy it is to start? You can use it on your first 200 endpoints, for free, forever, with no functional limits. It’s not a disguised free trial. No credit card required, no hidden limits, no tricks.
All you have to do is visit on.action1.com/entrachat and get started today.
So, if you’re looking to automate patching at scale and get weeks— even months—of your time back, go to on.action1.com/entrachat and sign up for patching—that—just—works.
3️⃣ App Registration Deactivation (A Quietly Powerful Feature)
Microsoft added the ability to deactivate app registrations.
Instead of deleting an app (and losing configuration), you can now:
* Immediately stop token issuance
* Preserve metadata and permissions
* Investigate safely
* Re-enable without rebuilding
For incident response scenarios — especially in multi-tenant or MSP environments — this is a big step forward.
4️⃣ Conditional Access Behavior Changes
There’s also a change impacting tenants with Conditional Access policies targeting “All resources” but excluding certain apps.
Previously, certain minimal-scope apps could bypass enforcement under specific conditions.
That loophole is closing.
Admins should:
* Review message center notifications
* Audit legacy apps
* Validate MFA handling before rollout
As always with identity changes: being proactive is critical.
5️⃣ Sync Security Hardening (Hard Match Protection)
Microsoft is adding additional validation to protect against malicious hard matching scenarios in hybrid environments.
This reduces the risk of identity takeover via manipulated on-prem objects.
It’s automatic — but important to understand if you manage hybrid identity or MSP transitions.

Governance in Microsoft 365 has always been hard. Not because the tools didn’t exist, but because scale, complexity, and change made consistency almost impossible. As tenants grow, so do the challenges of configuration drift, manual admin changes, and inconsistent environments.
For years, admins have relied on scripts, tribal knowledge, and community-led solutions like Microsoft 365 Desired State Configuration (M365DSC) to manage this “policy sprawl”. While M365DSC was a groundbreaking open-source effort, it often faced a steep learning curve and lacked official Microsoft support.
Until now.
In this episode of Entra Chat, we sit down with Nik Charlebois, Principal Program Manager at Microsoft and the original visionary behind M365DSC. Nik now leads the charge for one of the most significant platform shifts in Microsoft 365 administration: Tenant Configuration Management (TCM).
Shadow IT and SaaS sprawl are outpacing IT teams
It can feel impossible to tackle these app governance challenges:📦 Entra ID isn’t secure by default💥 SaaS adoption & sprawl isn’t slowing down⌨️ Citizen Development keeps rising (hello, Copilot Studio!)🗑️ Vendors often don’t remove apps after uninstall🔃 Offboarding is inconsistent or doesn’t happen at all🥔 App governance is passed around like a hot potato
ENow AppGov Score shines a light on lurking risks, providing a free App Governance Benchmark Report for your Entra tenant. Reclaim control and protect against breach & disruptions. Free upgrade to Standard Tier for 7 days once you get your score.
What is Tenant Configuration Management?
TCM is Microsoft’s official “Config as Code” platform for M365. Built directly on top of the Microsoft Graph, it represents a new operating model for how tenants are governed.
Key features discussed in this episode include:
* Official Support: Moving beyond best-effort community maintenance to a fully supported Microsoft solution.
* Simplified Experience: Transitioning from cryptic MOF files to human-readable JSON templates, significantly lowering the learning curve for admins.
* Snapshot & Drift Detection: The ability to capture “snapshots” of your tenant’s current state and monitor for unauthorized changes.
* Automatic Remediation: Automatically reverting detected configuration drifts back to your defined “gold standard” state.
* Broad Coverage: Support for core workloads including Entra ID, Exchange, Intune, Purview, Defender, and Teams with more to come.
This isn’t just a new feature; it’s the evolution of tenant governance into a native, API-driven platform. Tune in to hear Nik explain how TCM is bridging the gap between community innovation and official enterprise-grade management.

In this episode, we sit down with Eric Woodruff, Chief Identity Architect at Semperis, to discuss the reality of achieving a 100% phishing-resistant environment. Over the course of just three months, Eric led a 600-person organization through a complete rollout of passkeys, Windows Hello for Business, and Platform SSO. This conversation moves beyond the technical “knobs and dials” to explore why organizational change management and C-suite buy-in are the true foundations of a successful identity modernization project.
Eric shares the creative strategies his team used to drive adoption, including a custom self-enrollment portal built with Power Platform that allowed early adopters to “dogfood” the technology. We dive into the “voluntold” phase of the rollout, where voluntary participation transitioned into mandatory policy, and how they used Power BI to track progress and identify “stragglers”. The episode also provides a transparent look at the technical hurdles encountered, from legacy application exclusions to troubleshooting older Android devices and niche browsers.
Looking ahead, we discuss the critical importance of protecting against “downgrade attacks,” where sophisticated phishing attempts try to bypass modern security by tricking users into traditional password entries. Eric emphasizes that the final mile of this journey—removing passwords entirely—is as much about supporting your helpdesk and documenting processes as it is about the technology itself. Whether you are managing a cloud-only tenant or navigating complex hybrid scenarios, this episode offers a practical roadmap for the future of enterprise identity.

Service principals worked for static apps, but AI agents are different—they make autonomous decisions using LLMs and require a new approach to identity and security.
In this episode of Entra Chat, Padma Parthasarathy, Product Manager for Microsoft Entra Agent Registry, explains why Microsoft created Entra Agent Registry and Agent ID, and how they provide identity, governance, and security for AI agents.
We cover agent collections, discovery policies, integration with identity protection, and how custom security attributes automate AI agent governance at scale. You’ll also see how agents discover other agents by skills, how global and quarantine collections control visibility, and why these capabilities are critical for enterprise AI security.
This is a must-watch (listen) for identity, security, and platform architects preparing for AI at scale.
