I can't find
anything on the portal site mentioning encryption. They claim:
>Private by design
>Portal was created with privacy, safety and security in mind. And it has clear and simple settings, so you stay in control.
and in the FAQ:
>Secure calls
>Facebook doesn’t listen to, view or keep the contents of your Portal video calls. Your conversations stay between you and the people you’re calling.
And they have lock icons all over the place bragging about the security. But not once does it mention any sort of encryption. Presumably it's encrypted in transit to and from Facebook's servers, but if it were end-to-end encrypted such that Facebook couldn't monitor it, you'd think they would mention that.
Is "We don't listen to your calls, but we could" what passes for security and privacy at Facebook? Or is there e2e encryption and they've for some reason chosen not to mention it?
I'll stick with Facetime and iMessage, thanks.
