To support the COVID-19 response, the NHS approached Sitekit Group to lead a consortium of providers to implement Digital Staff Passports to streamline and accelerate the sharing of information, allowing staff to move quickly without the burden of paperwork whilst maintaining the safety of patients.

In place of paper proofs, information is transferred securely by the staff member through their own smartphone, putting them in control of sharing. Security is maintained using Verifiable Credentials and Decentralised Identifiers – World Wide Web Consortium (W3C) standards that support a rapidly emerging capability to securely share personal information.

The success criteria for this project have demonstrated a reduction in direct and elapsed time, meaning staff are available to work sooner at multiple sites for a safe and sustained response to the COVID-19 vaccination program. The DSP has recently extended to Clinical networks because of this success criteria.


Issue and Verify Web App (Staff Passport Portal)

The Passport digital process required a new capability for hospitals to be able to issue and verify credentials, such as the special COVID-19 Employment Credential. Sitekit Group and partners built and delivered a Staff Passport Portal issue and verify service that is now deployed in over 100 hospitals around England. The Portal:
  • Enables HR Departments to access a staff member’s passport.
  • Allows a wallet on a smartphone to connect to the Portal so that a staff member can review and accept credentials into the wallet onto their phone, either face-to-face at HR or online.
  • At the NHS organisation the staff member is moving to, the staff member makes a connection with the hospital’s HR Staff Passport Portal and their credentials can be checked.
  • As well as the COVID-19 credential, the wallet contains a digitally signed photograph which is used as a traditional “eye-ball” check with the staff member – similar to the checks that are conducted at border control with a traditional passport.

Working with Workforce Systems

The COVID-19 Digital Staff Passport issue and verify service works with the Electronic Staff Record, which means that the HR staff member does not need to fill out an empty form of information. If the staff member is already on ESR, the attributes can be transferred to generate a Verifiable Credential that is issued to the staff member’s passport.

The approach used to develop the API that enables ESR integration and incorporate it into the COVID-19 Digital Staff Passport could be adopted to enable other services such as bank and rostering systems to directly issue credentials.

In the future we expect the Digital Staff Passport to support the issuing and verifying of credentials directly, such as DBS, GMC, and Post Office.


For COVID-19, Sitekit Group implemented the Evernym wallet and associated Sovrin network infrastructure. Sitekit has also led a proof of concept exploring the use of Microsoft Authenticator. Sitekit is testing alternative wallets and infrastructure from Microsoft, Trinsic, Yoti, and the Post Office.


Sitekit, along with our sister company Condatis, are proven digital identity leaders with a track record of developing, designing, implementing, and supporting identity solutions at scale for the UK Government and, more recently, the NHS. The Sitekit Group has delivered identity solutions to the Department for Work & Pensions, the Department for Food, Environment & Rural Affairs, and the NHS as part of the COVID-19 Digital Staff Passport program.

Sitekit has provided guidance to the NHS team at Blackpool Teaching Hospitals NHS Foundation Trust and NHS England & Improvement, based on our experience of delivering major digital transformation programmes. This support has been led by the Sitekit CEO and Product Owner as a member of the NHS project meetings. Sitekit has been able to provide expertise in areas where the NHS did not have the capability or capacity. These include training for adoption and end-to-end visual tools to support benefits realisation. Most importantly, a team from Sitekit undertook the GDS audit and Focus Groups on behalf of the NHS to ensure that user research was embedded into the delivery process during the development stage and used to test out the biggest assumptions about how the service works for its users.


The Staff Passport Portal is offered as Software as SaaS using Public Cloud infrastructure. The issue/verify service can be readily implemented at a site using a combination of automated deployment tools and implementation and training assets. Sitekit’s ITIL-aligned service desk provides 1st, 2nd, and 3rd level support for DSP live operation.

The Staff Passport Portal SaaS embraces the complexities of Verified Credential ecosystems, decentralised public key infrastructures, public/private key access, and revocation of credentials on multiple wallets and associated infrastructures. This complexity is largely hidden through APIs that offer interfaces and protocols that are familiar to developers such as Open ID Connect and OAuth.
