There are two types of user credentials.
The first type ( a user reference & PIN ) were automatically allocated to you by your employer. If you have lost or forgotten these please speak to your payroll manager. They will be able to re-issue them for you.
The second type ( a user name & password ) may have been created by you when you chose to register your own user name & password. If you have registered your own user name & password and you've lost or forgotten these then click on the following link : I've lost my user name & password
Enter the email address you entered during the registration process and a user name & password reminder or reset url will be sent to that email address.
