A Single Use license authorizes one person to use ArcGIS Pro on one machine, such as a desktop computer. Use on a second machine is not allowed.
The license also authorizes the same person to use other ArcGIS Desktop applications—ArcMap, ArcCatalog, ArcGlobe, and ArcScene—on two machines, such as a desktop and laptop computer. However, these applications may not be used on both machines at the same time.
Because ArcGIS Pro uses the Named User license type by default, a license conversion is required before Single Use licenses can be authorized. Licenses are converted in My Esri by the software license administrator.
