Many professors set up a separate, optional Turnitin link in your learning management system (Canvas, Blackboard, Moodle) specifically for draft checking. These links are explicitly configured not to save your paper to the repository.
Because that leak was so large, SEO scammers write articles titled "Free Turnitin Class ID and Enrollment Key 2021" to trap students looking for that specific leak.
This article does not endorse bypassing Turnitin's terms of service. The historical Class IDs mentioned are defunct. Always use plagiarism checking tools in accordance with your educational institution's guidelines.
This is the only legitimate way to use the system. Once a student uses these credentials, they are officially enrolled in that instructor’s class and can submit assignments directly to the appropriate assignment inbox.
When you submit a paper to a Turnitin class, the software often saves a copy to its global database. If you use a random public class key, your paper may be permanently stored in that account's repository. When you later submit the final version to your actual school account, Turnitin will flag your paper as 100% plagiarized against your own previous submission. Removing a paper from the repository requires administrator intervention, which is incredibly difficult to coordinate for an unauthorized account. 2. Privacy and Data Theft
If you are a student, you must obtain these codes directly from your school or instructor. You can typically find them in the following ways:
Turnitin operates on a strict, institutional subscription model. Individuals cannot buy private accounts, and valid class keys are not meant for the public.
Classes in Turnitin are not permanent. Each class has an end date set by the instructor, and when that date passes, students can no longer submit papers or enroll in the class. The default duration for all classes is six months, though instructors can extend this period if needed.
: If you upload your draft to a rogue class that saves submissions to the standard institutional repository, Turnitin indexes your paper. When you later submit the final draft to your actual school account, the system will flag your paper as 100% plagiarized against your own leaked file.
