[Dynamically Get The Invocation Code From External Php File]

I would also like to know if this is possible. If anyone could at least point me to which file is responsible for making this unique key.

[Users can switch to default manager]

I have just installed revive for the first time. When I login as admin i am acting as the 'default manager' and can switch to administrator. I added a advertiser and then created a user and then linked him to that advertiser. However when i login as that advertiser I have the option to work as 'default manager' and can see everything he can see. What am I missing? Every account i make almost has admin privileges as 'default manager'  whether its a website or advertiser.
