If you are a consultant, or work in an organization that performs recruitment for multiple clients, you can add separate accounts for each client and be able to access all clients from a single login. 

When registering new accounts, you will want to enter your own name and contact information in the required fields. To connect multiple accounts from one login, you must use the same email address for each of the accounts that you would like to connect.

Once the new account is active, you can log into your original account using the email address and password you created. Navigate to the Main Menu< select Switch Account

The list of available accounts will appear. Select the account you want to access. The first time you log in, you’ll need to enter the email address and password for that account. After that, if cookies are enabled on your computer, you’ll be logged in automatically on future visits. 

It's as easy as pie.
