Verifiable Credentials: The Next Evolution of Identity & Access Management

Identity & Access Management (IAM) has spent decades answering fairly simple questions: “Who are you?” and “What are you allowed to do?”

For the first question, the answer has traditionally involved a username, a password, perhaps a multi-factor authentication prompt, and a token issued by an Identity Provider (IdP). Once authenticated, an application receives a collection of claims — your name, email address, department, groups, or roles — and decides what you’re allowed to do.

This model has served the industry remarkably well.

But it has one significant limitation.

Every time you need to prove something about yourself, you must return to the Identity Provider.

Verifiable Credentials (VCs) modify that assumption by allowing trusted claims to travel with the user (in a wallet application) instead of remaining locked inside an identity provider.

Identity Is More Than Authentication

Authentication is only one piece of identity.

Organizations constantly need to verify facts such as:

• Is this person an employee?
• Are they a licensed physician?
• Do they hold a security clearance?
• Are they over 18?
• Have they completed mandatory training?
• Do they possess a valid professional certification?

Today, these answers often require querying a centralized directory or identity provider.

Verifiable Credentials take a different approach.

Rather than asking the issuer every time, the issuer creates a cryptographically signed credential that the user stores in a digital wallet. The user can later present that credential to any verifier, who independently validates its authenticity.

The issuer doesn’t need to participate in every transaction.

Selective Disclosure

Perhaps the most compelling feature of modern Verifiable Credentials is selective disclosure.

Suppose your employer issues a credential containing:

• Name
• Employee ID
• Department
• Job title
• Security clearance
• Employment status

A building security system may only need to know:

Employment Status = Active

A contractor portal may only require:

Security Clearance = Secret

Neither system needs your employee number, department, or job title.

Modern credential formats, such as SD-JWT VC and BBS Signatures, allow users to disclose only the information required for a particular transaction.

That’s a significant improvement over today’s “all-or-nothing” identity assertions.

A Better User Experience

Consider how many times you authenticate during a typical workday.

• Corporate portal
• HR application
• Expense reporting
• Learning management system
• Vendor portal
• Partner application

Each interaction typically involves another redirect to an Identity Provider.

With Verifiable Credentials, many of these interactions can become simple credential presentations.

Instead of authenticating repeatedly, users present cryptographically verifiable proof that they possess the required attributes.

Authentication still matters, but it doesn’t have to be the only mechanism for establishing trust.

Where IAM Fits In

Verifiable Credentials are not a replacement for Identity Providers.

In fact, most IAM systems are well positioned to become Credential Issuers.

An enterprise Identity Provider already knows:

• Employee identities
• Group memberships
• Organizational roles
• Training completion
• Employment status
• Device compliance
• Risk posture

Issuing these facts as Verifiable Credentials is a natural extension of existing IAM capabilities.

Existing directories remain the source of truth.

Verifiable Credentials become portable, cryptographically protected representations of that truth.

Enterprise Use Cases

Workforce Identity (B2E)

Employees receive digital credentials representing:

• Employment
• Department
• Job function
• Professional certifications
• Mandatory training completion

Applications verify those credentials without constantly querying corporate directories.

Partner Access (B2B)

External partners often require access to internal systems.

Rather than provisioning accounts everywhere, an organization can issue credentials proving:

• Vendor relationship
• Contract status
• Required certifications
• Authorized projects

The partner controls the credential while the verifier validates its authenticity.

Regulatory Compliance

Healthcare, finance, and government frequently require proof of qualifications.

Examples include:

• Medical licenses
• Security clearances
• Professional certifications
• Export control authorization

Verifiable Credentials provide a standardized, cryptographically verifiable way to communicate those qualifications.

Customer Identity (B2C / CIAM)

Consumers may eventually carry credentials for:

• Age verification
• Residency
• Student status
• Loyalty membership
• Subscription ownership

Rather than uploading copies of documents, users present proofs generated from trusted credentials.

Privacy by Design

Traditional identity systems often reveal far more information than necessary.

A driver’s license discloses:

• Name
• Address
• Date of birth
• License number
• Photograph

…when a retailer simply wants to know you’re over the legal age.

Privacy-preserving credentials reverse this model.

The verifier receives exactly the information required — and nothing more.

This aligns naturally with modern privacy regulations emphasizing data minimization.

The Standards Ecosystem

Verifiable Credentials aren’t one specification — they’re an ecosystem.

Some of the major standards include:

• W3C Verifiable Credentials Data Model: Defines the overall credential model.
• OpenID for Verifiable Credential Issuance (OID4VCI): Defines how wallets obtain credentials.
• OpenID for Verifiable Presentations (OID4VP): Defines how credentials are presented.
• SD-JWT VC: Enables selective disclosure using JSON Web Tokens.
• BBS Cryptographic Suite (BBS-2023): Supports selective disclosure and zero-knowledge proofs for Linked Data credentials.
• Status List specifications: Allow verifiers to determine whether credentials remain valid without requiring the issuer to observe every presentation.

Together, these specifications provide a complete framework for issuing, storing, presenting, and verifying digital credentials.

Challenges Ahead

Like every emerging technology, Verifiable Credentials still face challenges.

Organizations must answer questions such as:

• Where are wallets managed?
• How are credentials revoked?
• How are issuer trust lists distributed?
• What happens when a device is lost?
• How are credentials synchronized across multiple devices?
• How do enterprises govern credential lifecycles?

Fortunately, these are engineering problems, not fundamental flaws in the architecture. The standards ecosystem continues to mature, and vendors are rapidly building enterprise-grade solutions around these capabilities.

Summary

Identity has traditionally been centralized. Applications contacted Identity Providers whenever they needed to know something about a user.

Verifiable Credentials introduce a complementary model: trusted claims become portable, cryptographically verifiable, and controlled by the individual or organization that holds them.

For Identity & Access Management professionals, this isn’t the end of federation, directories, or identity providers. It’s the next logical step in their evolution.

Tomorrow’s IAM platforms won’t simply authenticate users. They’ll issue trusted digital credentials, manage their lifecycle, and participate in an ecosystem where identity is portable, privacy-preserving, and verifiable anywhere.

In other words, IAM is evolving from managing identities to issuing trust — and that’s a much more interesting job.
