Here is solid content you can use for a support ticket, forum post, or internal documentation regarding an EasyEDA activation file.
Note: EasyEDA (Standard/Professional) is primarily a cloud-based PCB design tool. Offline activation files are typically only required for the Enterprise Edition (air-gapped networks) or older standalone versions. If you are using the free online version, activation is automatic via login. easyeda activation file
Since EasyEDA Pro is a web-wrapper or an Electron app (JavaScript/HTML/CSS wrapped in a browser), it does not have a traditional binary "license check" to crack. To "crack" EasyEDA, a hacker would have to modify the server-side code (impossible) or rewrite the client to lie about the login status. Here is solid content you can use for
Because this is incredibly difficult to do without breaking the software, hackers take the easy route: They make you install malware instead. The Technical Breakdown of the Fakes Since EasyEDA

Because EasyEDA is cloud-native (Standard) or cloud-logged (Pro), injecting a fake activation file can desync your local cache. Users have reported losing entire projects because a "patch" corrupted their local database.
