I guess they have some criteria for security and they don’t want to “ship” features that are below that (SMS is the most insecure you can get).

Still better than iMessage or WhatsApp!

Do they require to have a backdoor into the actual app (on your phone) or into the servers.

I’m not sure how data is stored locally (probably encrypted tho), but some time ago the FBI demanded Signal to give them all of the data they had on a specific account. All they were able to get was the phone number of said account and the account creation date.

1. They used to have that functionality (and I loved it) but they removed it due to it “not being secure enough” for their standards

2. Signal can absolutely replace WhatsApp, Viber (although I never heard of it before), etc. It supports voice and video calls, and you can even screen share from desktop
