If you have forgotten your password or have never created a password before, you can request a (new) password via the "Forgotten password" link on the login page of your customer's Flow portal (screen image may differ in details):
In the next window, enter your email address/username and click the right arrow button. Ignore the "green check mark"; that is only a check whether this page is safe, and not that an e-mail has already been sent.
You will then be sent a link to a secure environment, where you can enter a personal strong password if your e-mail address is known to us as a user name.
