Hi,
Microflows can be selected for use in Navigation. For default home page simply press select and choose your microflow. Please note that the microflow will be used alot and must be kept as streamline as possible.
Hi Teuku,
hava a look at the documentation about login behaviour, here you can call a microflow once when the user logs in:

You can also do this in the Navigation, but this will also be called when users are pressing the home page button.
