Microsoft Defender’s identity theft monitoring is a consumer feature for eligible Microsoft 365 Personal and Family subscribers in the United States. It can watch selected personal details for breach exposure, provide credit-file alerts when credit monitoring is enabled, and connect users with identity-restoration support. Microsoft’s current support pages describe an established feature; the original announcement framed it as a service for U.S. subscribers at launch.
What does Microsoft Defender identity theft monitoring include?
Microsoft describes four components: dark web monitoring, credit monitoring, 24/7 restoration support, and identity theft insurance. The feature is accessed through the Microsoft Defender app or My Defender web portal; it is not a physical monitoring device.
Dark web monitoring
You choose personal information to monitor. Microsoft says it checks for selected details appearing in a breach and sends an alert with a breach report and recommended actions. Monitorable categories include email addresses, passwords, name, birth date, phone number, Social Security number, national IDs, driver’s license and medical IDs, bank and card details, passport numbers, and certain account credentials. Email address, full name, and date of birth are required to start monitoring. Microsoft’s setup guide explains the information categories and enrollment.
Credit monitoring
If you enable credit monitoring in addition to dark web monitoring, setup asks for your Social Security number. Microsoft says the service alerts you to potentially malicious activity on a credit file and attempts to associate an SSN with a new address or identity. The credit score is a single-bureau VantageScore 3.0 supplied by Experian, and the monthly credit report uses single-bureau data. The score is unavailable to users under 18 and to users without credit history. The device’s primary display language must be English for the credit feature described in Microsoft’s footnote.

Restoration support and insurance
The app provides a restoration-support phone number for help responding to dark web or credit alerts. Microsoft says users may receive full-service identity restoration if someone is using their personal details to commit fraud. Its support page describes insurance limits of up to $1 million for identity-theft-related costs and up to $100,000 for lost funds. Those are stated maximums, not guaranteed payments; coverage is governed by policy terms, conditions, and exclusions. The policy is underwritten and administered by American Bankers Insurance Company of Florida, an Assurant company. Microsoft cautions that insurance coverage may not be available in all jurisdictions. Microsoft’s support page links to the policy and summary of benefits.
Who can use the feature?
Microsoft identifies U.S. Microsoft 365 Personal and Family subscribers as eligible to turn on identity theft monitoring in Defender. Credit monitoring is listed as available in the U.S. and U.S. territories; the separate insurance caveat means availability of the feature should not be read as universal insurance coverage. Current eligibility and terms are described in Microsoft’s current Defender guidance.
Family organizers cannot onboard, view, or receive alerts about another family member’s credit monitoring. For dark web monitoring, family members above the statutory age—13 in the United States—must consent before their information is monitored.
How do I get started?
- Open the Microsoft Defender app or the My Defender web portal.
- Find the Identity theft monitoring card. If you already have a setup, Microsoft says to use the Credit monitoring card.
- Select Get started, create a profile, and accept the terms.
- Choose the personal-information types to monitor. Email address, full name, and date of birth are required. Provide an SSN only if you also want credit monitoring.
- To add a family member to dark web monitoring, open the Identity Details card and select that family member’s avatar. Obtain the required consent for family members over age 13 in the U.S.
What information does Microsoft receive?
Microsoft says monitored information is securely transmitted to Experian and that Microsoft does not see or keep the personal information. In Microsoft’s words: “When you add a piece of information to be monitored, we securely transmit that info to Experian®. Microsoft doesn’t see or keep your personal information.” This is Microsoft’s description of its handling; it is not an independent audit of the data flow. The feature is a Microsoft Defender service that works with Experian, rather than a standalone device.

Dark web alerts appear on devices signed in to Defender and in the app’s dashboard and Alerts & History. Credit activity alerts also arrive by email. For assistance with an alert, use the restoration-support phone number shown in the app; Microsoft says full-service restoration may be available when someone is using your personal details to commit fraud.
Quick Recap
What to weigh before turning it on
- You must provide the required identity details to start monitoring, and adding credit monitoring involves providing an SSN.
- Credit monitoring is a single-bureau offering, not a view of all credit bureaus.
- Family credit monitoring is private to each enrolled member rather than visible to the family organizer.
- The stated insurance ceilings are subject to policy terms and regional availability.
- Microsoft’s live eligibility, language, and coverage conditions can change; consult its current support page and policy documents when enrolling.
