If you are having trouble signing in, your institution may have recently migrated from iThenticate Classic to iThenticate 2.0.
When an institution migrates to iThenticate 2.0:
- Every user receives a "Welcome to Turnitin" email to activate their new iThenticate 2.0 account.
- Your iThenticate Classic account is deactivated, meaning you can no longer sign in at www.ithenticate.com once migration is complete.
If you are unsure which version of iThenticate your institution uses, please contact your account administrator.
Have you activated your iThenticate 2.0 account?
Sign in using your institution's unique tenant URL (for example: [yourinstitution].turnitin.com) provided in your welcome email:
- Open your institution's unique login URL.
- Enter your username and password.
Tip: Your username may not be your email address. Use the unique username you created when activating your account. - Select Sign in.
Forgot your username or password? Use the "Forgot Username" or "Forgot Password" links directly on your institution's unique login page.
If you cannot find your "Welcome to Turnitin" email, please check your inbox and spam/junk folders first.
If you still cannot locate it, contact your local account administrator and ask them to resend your activation invitation. Once you receive the email, follow the activation instructions before attempting to sign in.

Are you receiving a specific error message?
This error is usually caused by one of the following scenarios:
- Your institution is still using iThenticate Classic: Your login credentials may be incorrect.
Fix: Verify your details or reset your password on the Classic login page. - Your institution has migrated to iThenticate 2.0: Your Classic account has been deactivated because a new one is waiting for you.
Fix: Check your email for the "Welcome to Turnitin" invitation to activate your new account.
Note: If you cannot find the welcome email, contact your account administrator. They can confirm which version of iThenticate your institution uses and resend your invitation if needed.
This message usually means you are attempting to use an older activation link after a newer invitation email has already been generated.
Fix: Search your inbox for the most recent invitation email you received. If you still cannot find it, contact your account administrator to request a fresh invitation link.
This message indicates that your iThenticate 2.0 account has not been activated yet, meaning self-service password resets are not yet available for your profile.
Fix: Locate your original "Welcome to Turnitin" email and complete the initial account activation. If you cannot find the email, reach out to your local account administrator to have the invitation resent.
