Signal has started rolling out Signal Login, an optional registration method that allows users to create a Signal account without providing a phone number. The feature will be rolled out first on Android and will come to iOS later.

As we previously reported, Signal Login is not a free alternative registration method. Signal requires users who choose to register without a phone number to make a one-time payment. The price at launch is $2.99 / € 3.49, although this may vary by region and currency.

Okay and how would you get that private key?

By having access to an unlocked device: which means you also have access to all messages. Therefor this attack vector is not as big a deal as you are making it.

You are, by extension, saying that PFS is not as big a deal as you are making it. Do you have anything to back this up that Signal et al aren't aware of? Would you like to argue Delta Chat should stop arguing in favor of it too?

Seems super dangerous to assume security due to ignorance of harm, but okay, I guess, we can play "look for why".

With DeltaChat, you can get a private key just by accessing a file on a desktop client. Or a backup file . Then you can pass that onto a compromised server and restore chat history that wasn't present on the client or backup file.
