Mobile-ID is available in E-Signing through the authentication-based signing function. The authentication is performed using the E-Ident service, and the E-Signing service generates the signature and adds the signature to the document. As a customer, you only need to integrate towards E-Signing, but your customer configuration will be updated with an E-Ident setup as well.
To get started with authentication-based signing with Mobile-ID, please contact support and they will help you enable the service.
