In order to create an account you will have to open the application and click on 'Create one now'.
Lastly, click on 'Sign Up'.
A small green dialogue will be shown on the bottom left of the screen letting you know it is time to verify your email.
The following step is then, checking your inbox. There, you will find an e-mail from Wayports (please do check your Spam folder just in case).
Upon opening the e-mail, you will have to click on 'Confirm Account'.
Once you have clicked there, you can already go back to the application and log in with the credentials you set before.
