After your onboarding with your dedicated support representative, you should have been given administrative access to your OpenWater backend portal.
Most customer's have a domain such as example.secure-platform.com. Your administrative login exists at example.secure-platform.com/a/admin. Take note of the /a/admin at the end of the url. Login with your email address and the password that was randomly generated and email to you.
If you forgot your password, click lost password? or contact your support representative at firstname.lastname@example.org if you need further assistance.
