If you have an existing student account, you can sign in with your Clever account to link them together.
1. Go to play.prodigygame.com and click Log in.
2. Then, click on the Clever button.
3. From here, enter the Clever information for your school or use your Clever Badge.
4. Then, enter your Clever login information.
5. Click on "I have a Prodigy account"
6. Enter your Prodigy username and password.
Since you're linking a student account, you'll want to input a Prodigy username and not an email. Using the email address could cause a conflict and not link properly in the system.
And you're done! You can now proceed to play with your account!
