Is there any news or comments from F-Secure regarding this feature? It would be really beneficial to have support for the Touch ID.
The new macOS IDP client is being developed and should be out in the coming months. This new client will contain new IDP feature module.
Once we get the new client out, that codebase is much better basis for further development, and also the codebase is partly same as in iOS client which already has touch ID. So, fingers crossed!
