To log on to Partner Central, go to https://central.plesk.com and enter your credentials.
Note: Partner Central has a single sign-on with Key Administrator. If you were using Key Administrator before, you need to enable global login in your account settings in Key Administrator to be able to log on to both Partner Central and Key Administrator, if necessary.
The Partner Central’s UI is organized by tabs (Home, Manage Licenses, and so on) that are located at the top of the screen.
The name of the current customer is displayed to the left of the tabs. If you have permissions to manage licenses of other customers, you will be able to select another customer. For details, see Working with Multiple Customers.
