if I want to check on them, I can log out and see everything, or perhaps visit their profile specifically.

when people use the word "authorized" in the context of computer systems, especially lawyers, they're not talking about the possibility of reprimand from your boss, they're talking about the Computer Fraud and Abuse Act, which has been interpreted by courts to mean that you need explicit permission granted by the owner of a computer even to access data served unsecured on the open internet.
and no, 200 OK doesn't count as explicit permission. it doesn't matter who you are or who you work for or what set of entirely legitimate keys you may have, explicit authorization outside the system always applies if you don't want to catch a felony.
