Connecting to CRM Online instances where authentication is MFA.
If the CRM instance implements MFA, the XRMToolkit fails to connect to the CRM Instance. Need to have different Authentication types enabled for XRMToolkit.
You can try out the beta of V6 by installing the following: https://xrmtoolkit.com/downloads/xrmtoolkit_6_0_0_11.vsix

If MFA is supported in the plugin registration tool, I think it should be here as well.
