Please Update Your Password


Security Incident

On November 3, 2026, our technical team detected unauthorized access to our web platform. We immediately launched an investigation, contained the issue, and patched the security vulnerabilities to prevent further access.

What Information Was Involved?

Our investigation indicates that account profile details—including names, email addresses, and encrypted password records—were accessed. We do not store financial information, payment card details, or sensitive government IDs on our platform, and none of this information was involved.

What We Are Doing

As a proactive security measure, we have invalidated all existing passwords across the platform to ensure unauthorized access cannot occur.

What You Need to Do

  • Reset Your Password: The next time you visit LearningTrajectories.org, click Forgot Password to set a new, strong password.
  • Review Password Reuse: If you used the same password on LearningTrajectories.org or your personal email, school accounts, or other websites, we strongly recommend updating those passwords as an added precaution.

Protecting the security and privacy of our community is our highest priority. We apologize for the inconvenience this causes and appreciate your prompt attention to updating your account. If you have any questions or experience difficulties logging in, please reach out to our team directly at mce.lt2@du.edu.
