PhishTitan has two levels of access - MSP and Customer, one of which your login account is based on. An MSP admin can drill down from the MSP level to the customer level to view and manage their customer accounts. See PhishTitan Levels of Access.
There are a number of options to move between the MSP and Customer levels:
Breadcrumb: You can travel up and down levels using the breadcrumb at the top of the page.
Menus: Select a customer from the All Customers menu. Use the breadcrumb to navigate back to MSP level.
Overview page: An MSP Admin can select the view icon for a customer in the All Customers table. Use the breadcrumb to navigate back to MSP level.
