Step 3: Navigate to the Account Access page
Click on the Tools & Settings icon 
and select Account access from the menu.
Step 4: Click the Add User icon
Click on the Add User icon.
Step 5: Select permissions and invite the user
Enter the individual's email address. Beneath the email field, select the level of access you want the individual to have. Grant Admin access only if you're comfortable giving the individual the ability to add users, delete users, and change user permissions.
When you're done, click the SEND INVITATION button located at the bottom left hand corner of the page. The individual will receive an email containing instructions on how to complete the setup process.
