Hermod is a web-based service for online authentication and signing using Smart ID Mobile App or Nexus Personal Desktop Client. Hermod allows for example the same processes, APIs, and workflows to be used for mobile and desktop (smart card, soft token). 

The Smart ID Messaging API overview is an easy-to-use business-oriented REST API for authentication, signing, and provisioning use cases. Hermod supports callbacks to avoid extensive polling.

Hermod is included as an architectural component in most Nexus products such as Smart ID Digital Access component, Smart ID Identity Manager, Nexus GO services, Nexus Personal Desktop, and Smart ID Mobile App.
