ArcGIS pro has two licensing options. The Named User License authenticates registered users through an organizational ArcGIS Online account. An ArcGIS Pro license must then be activated in your ArcGIS Online account..
Instructions for each of these methods are below.
Set up an account with Enterprise Login
With a Concurrent Use License, ArcGIS Pro will check with a license server (gislicense.nicholas.duke.edu) each time you open it, in order to verify that you have a licensed copy. You will still need to create an ArcGIS Online account and log in to ArcGIS Online if you want to move content back and forth from ArcGIS Pro on your desktop and ArcGIS Online in the cloud.
You may have an option to set up the license when you install the program.
After installation, you can always change the licensing option from within the ArcGIS Pro interface.
|From the opening interface, you can choose the Settings link in the lower left to get to the "About ArcGIS Pro" settings screen.|
|OR from the project interface you can choose the Project tab to get to the settings.|
|Then, choose the Licensing tab.|
|Then click on "Configure your licensing options" button at the bottom of the resulting screen.|
|Finally, you get a dialog where you can choose the licensing option and set the license manager address, which is gislicense.nicholas.duke.edu|
