With Mouseflow, it's possible to create and manage multiple user accounts. Each sub-user can be given 1 of 4 different types of access to one or more of your websites.
You can read about the different access types here.
To remove an existing user, perform the following steps:
Navigate to your User overview, here.
Click the "Delete" button on the right on the User you'd like to remove.
The user is immediately removed.
