Depending on how your organization has decided to onboard users, you might get an activation link or you can request a virtual smart card or other token via Smart ID Self-Service.
Virtual smart cards in Smart ID Desktop App are based on Microsoft Virtual Smart Card (VSC)and Universal Windows Platform (UWP) technology and use the Trusted Platform Module (TPM) chip, which is available in many computers, rather than requiring a separate physical smart card and reader. The solution uses native Microsoft mini-driver for communication with the VSC.
A virtual smart card that is provisioned with the relevant certificates, can be used by Microsoft Base Smart Card Cryptographic Service Provider (BaseCSP) for most Windows-related use cases. See Features of Smart ID Desktop App.
