A User account is for a day-to-day user of the system. They should be primarily contained to those within your immediate company.

A Partner account is an external user of the system, such as a marketing firm or reseller. Because they are not part of your immediate company that signed up for mobileStorm, their access is restricted to only a couple of areas in the system: Campaigns and Reports. It is not a requirement to have either of these accounts set up but we strongly recommend you create these accounts for a few reasons:

1. To allow more people to access the system other than yourself (should you be run over by the proverbial bus).

2. To limit access to various sections in your mS account such as Export Database and Billing Information.You might not want everyone in your company or folks in a partner company to access these two sections 

3. For security and logging-in purposes you should  not share your personal user name and password with anyone else.  If they did something naughty in your account it will appear that you were the culprit! Yikes!
   

   
   

An admin user is the individual who is officially registered to your mobileStorm account. The admin account administrates the use of the account and can make any changes to the account. This includes updating billing information, creation of User and Partner Accounts and creating and new campaigns.
