To enable sign in using the certificate authentication method, you configure SSL passthrough on the load balancer for the port defined on the Install SSL Certificate > Passthrough Certificate tab in the VMware Identity Manager console.
Enabling certificate authentication for a VMware Identity Manager on-premises deployment requires setting SSL pass-through at the load balancer. Upload a root certificate and intermediate certificates and private key to Passthrough Certificate tab. For more information about configuring SSL pass-through with a load balancer, see the Deploying VMware Identity Manager publication.
You can also upload a certificate to be used for Android SSO device authentication. See the Android Mobile Single Sign-on to VMware Workspace ONE publication.
