Rethinking Digital Identities

Digital identities are evolving. While identity data is often managed centrally by companies or platforms today, decentralized identity models give identity holders greater control over their own data.

Decentralized Identities and the European Digital Identity Wallet (EUDI Wallet) open up new possibilities for digital credentials, authentication, and the secure exchange of identity information.

What Are Decentralized Identities?

In decentralized identity models, identity information is not necessarily stored permanently in a central system. Users can manage digital credentials in a wallet and selectively present them to other parties when needed. For organizations, this creates new opportunities – but also new requirements for processes, architectures, and existing IAM structures.

Challenges for Organizations

With the introduction of the EUDI Wallet and the requirements of the eIDAS 2.0 Regulation, decentralized identities are becoming increasingly important. Many organizations are facing questions such as:

  • What impact will eIDAS 2.0 have on our organization?
  • Which use cases are suitable for Verifiable Credentials?
  • How can existing IAM systems be integrated?
  • What technical and organizational prerequisites need to be established?

What We Can Do for You

  • Analyze existing IAM environments
  • Advise on EUDI Wallet and eIDAS 2.0
  • Integrate Verifiable Credentials
  • Introduce decentralized identity concepts
  • Support pilot projects and Proofs of Concept
  • Integrate with existing business processes
  • Advise on regulatory requirements

EUDI Wallet in Practice

With the European Digital Identity Wallet (EUDI Wallet), the European Union is creating a common framework for digital identities. In the future, citizens will be able to securely manage identity credentials, entitlements, or certificates in a digital wallet and present them to public authorities or organizations.

For organizations, this means preparing existing processes for the use of digital credentials and creating new opportunities for identity verification.

Areas of Application

  • Digital identity credentials
  • Account opening in the financial sector
  • Public administration and government services
  • Healthcare
  • Universities and educational institutions
  • Telecommunications
  • E-commerce
  • Digital contract signing

EUDI Wallet and New Digital Identities

The European digital identity is intended to enable citizens and organizations to use digital identity credentials securely.

Organizations therefore need to consider at an early stage how new identity models will affect their digital services and existing IAM structures.

Benefits

The use of decentralized identities creates the foundation for secure and privacy-friendly digital business processes. Organizations can benefit from:

  • Greater data sovereignty
  • Reduced administrative effort
  • Standardized identity credentials
  • Higher security
  • Support for regulatory requirements
  • Interoperable digital identities

OEDIV SecuSys as a Partner for New Identity Models

OEDIV SecuSys focuses on the technological and organizational implications of decentralized identities and supports organizations in assessing how new developments can be incorporated into their IAM strategies.

What Is a Decentralized Identity?

A Decentralized Identity is a digital identity whose credentials are not held by a central provider, but in a digital wallet belonging to the identity holder. Instead of registering with each service using a username and password, the holder presents cryptographically signed credentials, such as proof of identity, age, a driving license, or affiliation with a company, and discloses only the data the service actually needs.

The European Digital Identity Wallet (EUDI Wallet) is the digital wallet for identity credentials that each EU Member State must provide based on the eIDAS 2.0 Regulation. Citizens and businesses can store identity data and credentials such as driving licenses, educational qualifications, or corporate powers of attorney and present them online and offline. Member States must make the wallet available by December 24, 2026. Germany plans to launch it in early 2027. Use of the wallet is voluntary for citizens.
The eIDAS 2.0 Regulation requires companies in certain sectors to accept the wallet as an identification method when they require strong user authentication: banks and financial service providers, insurance companies, telecommunications, energy, transport, postal services, digital infrastructure, healthcare and social security, education, and very large online platforms. The acceptance requirement for private companies takes effect on December 24, 2027, one year after the wallet is made available by the Member States. Micro and small enterprises are exempt. For everyone else, use of the wallet is voluntary, but it offers an opportunity to simplify registration and identity verification.
Verifiable Credentials are digital credentials that are cryptographically signed by the issuer and whose authenticity can be verified by any recipient without contacting the issuer. One example: a university issues a degree as a credential, the graduate stores it in their wallet, and an employer verifies the university’s signature. The underlying standards come from the W3C web standards organization and, for mobile identity documents, from the ISO standards organization.
With a traditional login, each service stores its own account with a password and profile data, and the service retains the data. With a wallet, the user holds the credentials themselves and discloses only what is necessary for each transaction — for example, “over 18” instead of their date of birth. The service verifies the issuer’s signature and does not need to store a copy of the identity data, reducing privacy risks and liability.
Identity verification during the onboarding of customers, partners, and employees can be replaced: instead of requesting a copy of an identity document and video identification, the system verifies a credential from the wallet within seconds. Storing less personal data means lower privacy risks. In the business customer environment, powers of attorney and company affiliation can be verified automatically. Organizations planning a customer identity solution today should provide for wallet integration as a login option. We take this into account in every architecture for Customer Identity & Access Management.
Integration is carried out via a verification component that requests and verifies credentials from the wallet, using standard protocols such as OpenID for Verifiable Presentations. It is connected to the existing authentication service or customer identity platform, allowing the wallet to appear as an additional login and verification option alongside passwords, passkeys, and third-party login. We are already implementing requirements arising from the eIDAS Regulation today, such as qualified electronic signatures using smartcards and smartphones, and support you with the architecture, component selection, and integration of the wallet.
