[General spies] Why does everyone just answer the phone and talk freely?

James Bond is a good example, he just uses the phone and assumes he is talking with MI6. No security handshake, no tests for people being under duress. Nope, just go straight to talking about secret stuff.

Wouldn't intelligence agencies be more cautious about this? I would expect at least two factor authentication: "This is James Bond, security code Delta-5-7-Alpha requesting contact with officer Lima-8-2-Tango" And then they change the codes daily/weekly/etc.

All of that is already in the phones they get issued. When they have to use public phones, they go through all that hassle but if they’re just using their issued phone, they just assume all that stuff has been handled already.
