Microsoft Entra Verified ID Guide: Architecture, Use Cases, and Best Practices

For decades, digital identity has relied on a model where a single, centralized authority—be it an employer, a government, or a social media platform—vouches for who you are. You prove your identity by presenting a username and password, or by delegating that proof to a federated login provider. This model, while functional, creates significant friction when you need to prove something specific—like your age, a professional certification, or your employment status—without revealing your entire identity. It also concentrates sensitive personal data in central repositories, making them attractive targets for attackers.

Microsoft Entra Verified ID is Microsoft’s implementation of a decentralized identity system built on open standards. It allows organizations to issue digital credentials—called Verifiable Credentials—that individuals can store in their own digital wallet and present to any service that trusts the issuer. This guide explains the architecture, trust model, and practical applications of Verified ID from an engineering perspective, preparing you to design and integrate privacy‑preserving identity workflows into your applications.

Why Digital Identity Needs to Evolve​

The traditional identity model has several well‑known weaknesses:

  • Password fatigue and phishing: Users manage dozens of passwords, often reusing them. Phishing attacks trick users into revealing credentials, bypassing even multi‑factor authentication in some cases.
  • Centralized identity silos: Identity providers (IdPs) like Google, Facebook, or corporate Entra ID tenants hold vast amounts of user data. A breach at any one of them exposes millions of identities.
  • Over‑sharing of information: When you prove your age by showing a driver’s license, you also reveal your name, address, and license number. The verifier receives far more data than they need, creating a privacy risk.
  • Repetitive verification: Educational institutions, employers, and government agencies repeatedly re‑verify the same credentials—degrees, background checks, professional licenses—because there is no standard, portable way to carry those proofs.

Decentralized identity addresses these problems by decoupling the issuer of a credential from the verifier who needs to check it. The subject (you) holds the credential and controls when, where, and with whom it is shared. This model is often called Self‑Sovereign Identity (SSI).

What Is Decentralized Identity?​

Decentralized identity is a system where individuals and organizations create and control their own digital identifiers without relying on a single central authority. It is built on three foundational technologies:

  • Decentralized Identifiers (DIDs): A DID is a globally unique identifier that an entity creates and controls independently. Unlike an email address, which is issued by a provider, a DID is self‑owned. DIDs are typically stored on a distributed ledger or a blockchain, making them tamper‑evident and resolvable to a DID document that contains public keys and service endpoints.
  • Verifiable Credentials (VCs): A VC is a tamper‑proof digital statement made by an issuer about a subject. It is cryptographically signed, so anyone who trusts the issuer can verify its integrity and authenticity. A VC can represent a diploma, a membership card, a work permit, or any other attestation.
  • Trust Frameworks: A trust framework is a set of rules, governance documents, and technical standards that define how participants—issuers, holders, and verifiers—interact within a decentralized identity ecosystem. It ensures that credentials are issued and verified according to agreed‑upon policies.

In a decentralized identity transaction, three parties interact:

  1. Issuer: An organization that attests to a set of claims about a subject and packages them into a verifiable credential. A university, for example, is the issuer of a diploma.
  2. Holder: The individual (or organization) that receives and stores the credential in a digital wallet. The holder controls the credential and decides when to present it.
  3. Verifier: A service or application that requests a credential from the holder, verifies its signature, checks its revocation status, and then makes a trust decision based on the claims inside it.

Microsoft Entra Verified ID at a Glance​

Microsoft Entra Verified ID provides a managed service for issuing and verifying Verifiable Credentials in Azure. It is integrated with the broader Microsoft Entra ecosystem but operates on open standards, allowing it to interoperate with other decentralized identity systems.

The platform provides the following roles:

  • Issuer Service: Enables an organization to define credential schemas, authenticate a user (via Entra ID or other means), and issue a signed VC to the user’s wallet. The most common wallet is Microsoft Authenticator, but the system supports any wallet compatible with the open standards.
  • Verifier Service: Provides APIs for a relying party to generate a presentation request—a query asking for one or more specific credentials with certain claims—and to validate the response. The verification logic checks the issuer’s DID, the signature, the credential’s expiration, and its revocation status.
  • Credential Types and Schemas: Organizations define the structure of their credentials (e.g., a “VerifiedEmployee” credential with claims for firstName, lastName, employeeId, and department). These schemas are published so verifiers know what to request.
  • Trust Registry: A decentralized ledger (currently ION, which runs on the Bitcoin blockchain) anchors DIDs and their associated public keys, providing a universal trust anchor that does not depend on a single provider.

Core Architecture​

The architecture of Entra Verified ID follows the standard decentralized identity model, with Azure providing the cloud infrastructure for issuers and verifiers.

  1. Issuance: The user authenticates to the issuer’s application (often using their existing Entra ID account). The issuer service creates a verifiable credential, signs it with its DID, and sends it to the user’s wallet. The issuer’s DID and the credential schema are anchored on the ledger.
  2. Storage: The user stores the VC in their digital wallet. The wallet holds the private keys that control the user’s own DID.
  3. Presentation: The user visits a verifier’s application (e.g., a website requiring proof of employment). The application generates a presentation request specifying the required credential type and any required claims. The user’s wallet receives this request and, with the user’s consent, prepares a verifiable presentation—a cryptographic proof derived from the VC.
  4. Verification: The verifier service receives the presentation, resolves the issuer’s DID from the ledger to obtain the public key, validates the signature, checks expiration and revocation, and extracts the requested claims. The relying party application then makes its authorization decision.

Core Concepts​

To design with Verified ID, you must understand the following primitives:

  • Decentralized Identifier (DID): A globally unique, resolvable identifier that is not tied to any central provider. Entra Verified ID uses the did:ion method, which anchors DIDs on the Bitcoin blockchain via the ION network, ensuring long‑term, censorship‑resistant availability.
  • Verifiable Credential (VC): A cryptographically signed set of claims about a subject. It contains the issuer’s DID, the subject’s DID (or an identifier that the subject controls), the claim values, and metadata such as issuance and expiration dates. The integrity of the VC can be verified by anyone who trusts the issuer.
  • Credential Manifest: A document published by the issuer that describes what a credential means, what claims it contains, and how it should be displayed. Wallets use the manifest to render credentials in a human‑readable format.
  • Presentation: When a holder shares a credential, they generate a verifiable presentation. This is a proof—often a signed wrapper—that demonstrates possession of the credential without necessarily transmitting the raw credential itself, supporting selective disclosure of claims.
  • Revocation: Entra Verified ID supports a revocation mechanism based on the issuer updating a status list. During verification, the verifier checks this list to ensure the credential has not been revoked since issuance.

Credential Lifecycle​

Every VC moves through a predictable lifecycle.

  1. Identity Proofing: The issuer verifies the subject’s identity and attributes using trusted processes. This could be an HR onboarding workflow, an in‑person ID check, or a federated login to an existing system.
  2. Credential Issuance: Once proofed, the issuer generates a VC containing the attested claims and sends it to the subject’s wallet. The subject must accept and store it.
  3. Storage: The VC resides in the subject’s wallet. The wallet holds the keys that prove ownership of the subject’s DID, preventing the credential from being used by anyone else.
  4. Presentation: The subject decides to share the credential, or a subset of its claims, with a verifier. The wallet generates a proof that satisfies the verifier’s request, typically after the subject explicitly consents.
  5. Verification: The verifier validates the proof, checks the issuer’s trustworthiness, confirms the credential is not revoked or expired, and extracts the needed claims.
  6. Expiration and Revocation: Credentials have an expiration date, after which they should not be trusted. They may also be revoked early if the subject’s status changes (e.g., an employee leaves the company). The verifier must always check for both.
  7. Renewal: Before a credential expires, the subject may go through a re‑proofing or re‑issuance process to obtain an updated VC.

Microsoft Entra Verified ID Components​

The Entra Verified ID service is composed of several key sub‑systems:

  • Verified ID Service: The Azure‑hosted control plane where you configure your organization’s DID, define credential schemas, manage issuance and verification policies, and monitor usage.
  • Issuance and Verification APIs: A set of REST APIs that your applications call to issue credentials or to validate incoming verifiable presentations. These APIs handle the complexity of DID resolution, cryptographic validation, and revocation checks.
  • Microsoft Authenticator: The primary digital wallet for Entra Verified ID. It securely stores DIDs, keys, and VCs on the user’s mobile device, providing a familiar interface for receiving and sharing credentials. The system also supports interoperability with other standards‑compliant wallets.
  • ION (Identity Overlay Network): The decentralized public key infrastructure that underpins the did:ion method. ION runs as a layer‑2 network on top of the Bitcoin blockchain, providing a scalable, globally accessible trust anchor without relying on a single Microsoft service.

How Verification Works (in detail)​

The verification flow is the core security transaction.

  1. The verifier application creates a presentation request specifying the required credential (e.g., a VerifiedEmployee credential). The request is signed to prevent tampering.
  2. The user presents their wallet (e.g., by scanning a QR code) to retrieve the request.
  3. The wallet decodes the request, finds the matching credential, and asks the user to consent to sharing it.
  4. Upon consent, the wallet generates a cryptographically signed proof, which may include all or a subset of the credential’s claims.
  5. The verifier service validates the proof by:
    • Resolving the issuer’s DID to obtain their public key.
    • Verifying the proof signature to confirm the credential was issued by that DID and has not been tampered with.
    • Checking the credential’s validity period and revocation status.
  6. The verifier returns the extracted claims to the application, which makes its authorization decision.

Security Model​

Entra Verified ID’s security rests on several layers:

  • Public Key Cryptography: The issuer signs a VC with their private key. The verifier uses the issuer’s public key—obtained via DID resolution—to verify the signature. The holder signs a presentation with their own private key, proving they control the subject DID.
  • Privacy by Design: Credentials are stored on the holder’s device, not in a central database. The issuer does not inherently know when or where a credential is presented. Verifiable presentations support selective disclosure, allowing the holder to prove, for example, that they are over 18 without revealing their exact birthdate.
  • Tamper Resistance: Cryptographic signatures make it computationally infeasible to alter a VC or create a fake one.
  • Replay Protection: Presentations include nonces and timestamps, preventing an attacker from capturing and replaying a proof.
  • Revocation Lists: Issuers maintain a cryptographically signed revocation list. Verifiers must check this list to ensure a credential has not been revoked, even if it hasn’t yet expired.

Integration with Microsoft Entra ID​

It is crucial to understand that Verified ID does not replace Microsoft Entra ID. Entra ID remains the identity provider for your workforce, managing authentication, Conditional Access, and role‑based access control to Azure and Microsoft 365.

Verified ID extends these capabilities into the realm of portable, third‑party verifiable attestations:

  • Issuance: You can integrate the Verified ID issuance flow with an Entra ID user’s sign‑in. For example, after an employee completes a compliance training in an internal portal, the system can issue a verifiable credential attesting to that fact.
  • External ID: Verified ID is a natural complement to External ID for B2B scenarios. A partner organization can issue a VC to its employees, who can then present it to your applications, eliminating the need for you to create and manage guest accounts for them.
  • Conditional Access: Currently, Verified ID is a separate trust decision. In the future, the claims from a verified credential could feed into a Conditional Access policy—for instance, requiring a valid employee credential and a compliant device before granting access to a high‑value application.

Enterprise Use Cases​

  • Employee Identity: A company issues a “Verified Employee” credential. Employees can use this to access partner services, unlock building access, or prove their corporate affiliation without sharing their corporate password.
  • Education: Universities issue digital diplomas as VCs. Graduates can share their degree with employers or background‑check agencies instantly, without the employer having to call the registrar’s office.
  • Professional Certifications: A cloud provider or industry body issues a certification credential (e.g., “Azure Solutions Architect Expert”). Job seekers can present a tamper‑proof proof of their certification.
  • Partner and Vendor Onboarding: A large enterprise requires its suppliers to hold a “Verified Supplier” credential. New suppliers obtain the credential once and can onboard with multiple customers quickly.
  • Healthcare: A patient holds a verifiable vaccination record. They can share their vaccination status with a gym, a travel agency, or a concert venue without exposing their entire medical history.
  • Government Services: Citizens hold a digital ID credential. They can use it to log in to all government services, file taxes, or prove their residency.

Verified ID for AI and Cloud-Native Applications​

AI agents and autonomous workflows often need to act on behalf of a user, calling APIs and accessing data. Verified ID provides a mechanism for these agents to carry a portable, cryptographically verified proof of their authority.

  • Agent Authorization: A user issues a verifiable credential to their personal AI assistant, granting it specific permissions (e.g., “authorized to schedule meetings”). The AI can then present this credential to the calendar service without needing the user’s full credentials.
  • Machine‑Verifiable B2B Automation: An autonomous supply‑chain system can issue a “Quality Inspection Passed” VC for a batch of goods. The logistics system can automatically verify this credential upon receipt, triggering payment without human intervention.
  • Identity‑Aware Retrieval Augmented Generation (RAG): An enterprise RAG chatbot presents a user’s VC to the retrieval service, ensuring it only searches the document repositories the user is authorized to see. This embeds fine‑grained, cryptographically enforceable data boundaries into the AI pipeline.

Common Architecture Patterns​

Employee Onboarding: An HR system verifies a new hire’s identity documents, then calls the Verified ID API to issue a WorkEligibility credential to the employee’s wallet. The employee presents this to IT to receive their laptop.

University Diploma: The student information system issues a digital diploma upon graduation. The alumnus shares it with a background‑check firm. The firm’s API verifies the signature against the university’s DID.

Cross‑Company Trust: Two partnering companies exchange DIDs and agree on a credential schema. Company A issues a ProjectClearance credential to its consultants, who present it to Company B’s project portal for access.

Customer Identity Verification: A bank requires new online customers to prove their identity. A government‑issued digital ID credential (a VC) is presented, verified, and used to populate the account application, reducing manual data entry and fraud.

Microsoft Entra Verified ID vs Traditional Identity​

Currently, Azure is the only major cloud provider offering a fully managed, standards‑based verifiable credential service deeply integrated with its identity platform. Both AWS and Google Cloud offer blockchain services that could be used to build a custom solution, but they lack a turnkey CIAM‑integrated offering.

Best Practices​

  • Minimize the claims in a credential. Issue only what a verifier actually needs. Over‑loading a credential with unnecessary attributes creates a privacy risk.
  • Set appropriate credential expiration. Short‑lived credentials reduce the window of risk from a compromised wallet, but require more frequent renewal.
  • Design your revocation strategy early. Understand how you will revoke a credential when a relationship ends (e.g., an employee leaves). Ensure your verifiers always check the revocation status.
  • Separate identity proofing from credential issuance. The process that verifies a person’s real‑world identity should be rigorous and audited. The issuance of a digital credential is then a deterministic, automated step.
  • Trust governance is essential. Establish clear policies for which issuers you trust for which types of credentials. Do not trust every issuer for every claim.
  • Plan for wallet diversity. While Microsoft Authenticator is the primary wallet, understand the implications of interoperability with other wallets, particularly in cross‑company scenarios.
  • Monitor issuance and verification. Track the volume of credentials issued and verified, and alert on anomalies, such as a sudden spike in verification failures.

Common Mistakes​

  • Treating Verified ID as a replacement for Entra ID or Azure RBAC. It is an attestation layer, not an authorization or authentication replacement.
  • Issuing a single, monolithic credential with excessive claims. This forces the user to reveal all claims even when only one is needed. Break credentials down by use case.
  • Ignoring the revocation strategy. A credential without a well‑understood and enforced revocation path can provide a false sense of security.
  • Failing to validate all aspects of a presentation. Verifiers must check the signature, the issuer’s DID trust, the expiration, AND the revocation status. Skipping any one of these checks undermines the entire trust model.
  • No credential expiration. Permanent credentials are a long‑term liability. Always set an expiration and a renewal process.
  • Poor identity proofing. A verifiable credential is only as trustworthy as the process that verified the identity in the first place. A strong cryptographic signature on a lie is still a lie.

Practical Learning Path​

  1. Start with the fundamentals of cloud identity: Entra ID, authentication, and authorization.
  2. Learn the standard protocols: OAuth 2.0 and OpenID Connect.
  3. Understand the concepts of public key cryptography and digital signatures.
  4. Study the principles of Self‑Sovereign Identity (SSI) and the W3C Verifiable Credentials Data Model.
  5. Set up a test Entra Verified ID tenant and configure your organization’s DID.
  6. Issue your first verifiable credential to Microsoft Authenticator.
  7. Build a simple web application that verifies that credential.
  8. Design a more complex use case, such as an employee onboarding flow with multiple credential types.
