If you have forgotten your password, don’t worry, it is easy to get a new one. Just click on the Forgotten Password? link on the Sign in screen.
Enter the email address you used to register with the system (usually your work email), tick the “I’m not a robot” box and click the “Submit” button. You will then be sent an email to this address with details of how to reset your password.
If no email arrives after a few minutes, it maybe because the email has gone to your junk mailbox, so check there first. If it’s not there, it is likely that the email address you provided is not registered with the system.
