(Internship) TrustID MFA for RDP and Windows Logon


TrustID is an ELCA’s product delivering strong multi-factor authentication (MFA). It is particularly well-suited for external accesses. The privileged authentication factor is an OTP tightly coupled with the TrustID app.

In some specific scenario, we need to have MFA for logging to Windows workstation or RDP access. We would like to provide such feature to our clients.

Under Windows, user log-on is delegated to a module called credential provider ( We thus want to write such a credential provider that would use TrustID to implement the authentication.

In this role

  1. Understand Windows Logon & Credential Provider mechanisms
  2. Understand TrustID architecture
  3. Design a solution to be able to use TrustID authenticator through Windows Credential Provider
    1. Both online and offline mode must be functional
    2. Ideally, the designed solution should be able to support other kind of authenticator
  4. Implement this credential provider for TrustID mobile authenticator
  5. Document this new feature

Depending on time available, support of other kind of authenticator can be added.
