You can reset your password at any time by clicking "Forgot your password?" on the login screen. Then, enter your airline and the Employee ID or e-mail address you use to login, and you'll receive an e-mail with a link to reset your password.
(Please make sure to check your "spam" folder if you don't immediately see the password reset e-mail.)
If you can't remember the e-mail address or Employee ID tied to your ID90 Travel account, you'll need to contact our Customer Support team for further assistance.
