You can reset your password anytime by using the [Forgot your password?] link on the homepage and then follow the prompts. Alternatively you can reset it once you are logged into Purchase Plus.
To change your password through Purchase Plus, click on your name from the top menu bar on the right hand side of your screen and then from the drop down click [Change Password].
A screen will appear asking you to input a new password, once you have verified your new password click on [Save].
The password requirement must contain eight charters, a capital letter and a number.
Your password is now changed.
