Create an API Access user in ScreenSteps
An API Access user is a "shared" user that has the same permissions as a Reader user. The only difference is that when an API Access user is logged in they can not change their email or password.
Use this type of user when you want a simple way to give a group of people the same username and password.
Click on Account > Users
