## Support for UPN domains

Previously, the smart card authentication for unattended sessions matched the Orchestrator username only to the primary UPN. Changing the UPN domain required recreating smart cards.

You can now specify the UPN on the smart card in the **Domain\Username** field of your Robot account. Use the `ADUPN\some.upn@domain` format for private domains, or `AzureAd\some.Azure@domain` for Azure AD domains.

This update also allows specifying a UPN directly for authentication, regardless of whether password-based or smart card authentication is used.

However, when using smart card authentication with certificates, alternate UPNs are supported only if the certificate was issued to that alternate UPN.
