To reset your Travel Data Account Password, just visit the account login page here: https://traveldata.page/account/ and click on the Lost Your Password link to receive a link via email to reset your password.
WARNING: Be patient! Only press the "Get New Password" button once, and wait for it to submit! Requesting a password reset link for an invalid username/email or the same user/email address multiple times in a short period of time will result in a lockout, and you will need to wait before trying again. Support teams cannot assist with lockouts, you must wait.
