On the Agility Welcome page you will see a link saying 'Forgot Password? under the Sign In button':
Once this link is clicked, the next page will ask you to provide your username (the email address used to create your Agility account), and an email with your temporary details will be sent to this address.
If you do not receive an email, please check your Spam, Junk or Clutter folders. If the email has not been filtered to these folders, please contact the Agility Support Team via live chat or at firstname.lastname@example.org.
