You can add a new account directly on the platform. You can do this by clicking on Create Advertiser on the dropdown as per the screenshot below, or by navigating to Admin Tools > Create Advertiser.
You will then need to fund each account individually. 💰
Once created, you will be able to navigate to each account by clicking on the upper right dropdown, without needing to log out. 🌟
Additionally, you will be able to view the performance for all your accounts at once, under the Overview and Reporting pages. 🎉
