why cant people just download testflight and test? Everyone thinks im trying to steal their password

I thought people could just download testflight , get an invite and test an app.

They have to use their password on appstoreconnect which makes it look like a phishing attempt or some kind of hack.

is there any way to have the users not have to be brought to a website demanding their password?
