The username and password are system generated and will, therefore, be the correct combination.
When copying your username and password from the email you received, make sure that you do not copy in an extra space at the back, as it will be seen as part of the password.
We aimed to make the computer-generated passwords easy to remember and type, and therefore suggests that you manually type in the username and passwords to prevent the above problem from occurring.
TIP 1: Make sure your Caps Lock button is not activated.
TIP 2: Make sure you check the spelling of what you have typed. Sometimes applicants swap letters or numbers around which leads to a login decline.
