How DevTools licenses work and who should be licensed?
Progress Telerik product licenses are perpetual and within the first 12 months include product updates (new features and fixes) and technical support. Support can be received via our online ticketing system with 24 to 72 hours turnaround time or over the phone if your license allows it. Additional access to product updates and technical support can be purchased with the initial license purchase or later, which will extend the maintenance within the desired period. You can contact us to discuss your specific case at Telerik-sales@progress.com.
The license holder can assign license developers and managers through Your Account in the section Licensed Users and reassign them anytime. All assigned users will automatically receive credentials to log into the system. Also see the next question "What is the difference between license holder, developer and manager?"
