The original registering user will need to add additional users to the account.
To accomplish this:
- Login to Threat Explorer
- Click "Account" in the upper right hand corner.
- Looks for the "Add User" section
- Fill out their Email, First Name, and Last Name
- That will send an email to the user and they should be able to login
- If they want that user to be an admin their account will show up in the "Account Users" section above and they can promote them to an admin
- As well as other actions like: Resend Invite Email, Disable or Delete the account.
