TestEngine, from version 1.29 onwards, uses two types of licenses:
SmartBear ID-based - From October 2023, file-based licensing will be fully replaced by SmartBear ID-based licensing. SmartBear ID-based licenses are a new proprietary license management option we started using in ReadyAPI 3.8.1. It is more reliable and convenient than the license type used in the previous product versions. To run the product, a user needs to specify their access credentials based on the location of the License Server, with options for connecting to the SmartBear-hosted licensing server or an onpremise-hosted licensing server.
File-based - These licenses involve using a SmartBear license file. You apply that file on your computer to activate the license, or you consume the license from the license server running in your network, and that is licensed with this file.
