When installing Postman (on Mac), you can log on using your Google account. For this, the logon view from Google is shown in a window (A kind of Webview I assume).
How can I be sure this is the real thing and the developers did not just build an own webpage that looks exactly the same? Since there is no browser bar or anything like that, I can't verify the URL.
Now I was only sure of it after typing my username and password, when Google sent me an email notifying me of the new login.
PS: This is certainly not an attack at Postman, it is just what triggered my question.
