it didn't prompt me to change my password when i logged back in, so how can I change it? Thanks.
Before you attempt to change your PW, make sure you have access to the email that is on file with ECCIE when you registered. PW reset tool sends link to your email and that is how you reset it (use forgot password reset link).

If, on the other hand, you know your current password and just want to set a new one, log into ECCIE and click on the 'User CP' link in the Main Menu on the left side of the screen, then click on 'Edit Email and Password'. You should see a screen that asks you to enter your current password then your new password twice.
