Multiple logins for our account

Can I have multiple staff members login to manage our screens (with different usernames) or do I have to share my login for them to access the screens in our account?  If so, can I control their access:  such as Joe can only create content but not manage the screens and post content, etc.?

Thanks

This is something that we will be added sometimes this year.
