To get to the Link Personal Account option, click on the name icon in the top left corner. From the dropdown, click Account Settings. On the right-hand side of the page, click Link Personal Account. You’ll see a box pop up to enter your information.
If you already have an account, all you have to do is enter your credentials in the box. If you do not have an account, select your desired email and password to continue. Your name and city will be pre-filled from your corporate account, so you don’t need to provide that information here.
