Supported Extension

OpenID Connect (OIDC) Bridge

Take advantage of the power of digital credentials by using our OpenID Bridge to plug into your existing systems.

OpenID Connect is a widely used method for authenticating users in web applications, commonly seen in ‘login with social or email’ button.

This makes it easy for organisations to use their existing infrastructure and data, reducing the time it takes organisations to start using digital credentials.

EU Digital Covid Certificate (EUDCC)

We’ve built support for the EU Digital COVID Certificate (EUDCC) on top of our core libraries as well as our capabilities such as key management and digital signatures.

The EUDCC was developed by the European Commission and EU member states as a way for EU residents to prove their vaccination status.

Flexible implementation options

Every organisation is different. We’ll work with you to implement our solution based on your needs. Talk to us about how we can best support you.

Here are some of our credential verification patterns:

  • Verify through push notifications using credentials saved in a mobile wallet.
  • API-driven verification using MATTR VII to carry out authenticity and revocation status checks.
  • Verification through existing systems or services using OpenID Connect.


Our approach

Support for different credential types
Our technology has built-in support for a variety of different credentials, making it easy to use whilst reducing operational risk.

Digital and paper-based credentials
We bridge the gap between your organisation and the existing ways people use credentials, whether that means a digital wallet on a smartphone or a physical document.

No vendor lock-in
Our open, decentralised technology prioritises interoperability, meaning you’ll never be locked in to one provider.

Your global technical expert
MATTR works with the global standards community, organisations and a range of technical experts to develop technology that’s interoperable and is aligned to best practices.
