Molly (fork of Signal) allows you to use multiple phones https://github.com/mollyim/mollyim-android

I used it for a couple years, but came back to signal because I had so many issues with media sharing.

FYI, the Pro has been discontinued: https://pine64.org/2025/08/14/august_2025_short_update/

I ran into facial recognition at the airport recently an opted out, but what are the likely and worst case consequences of allowing yourself to be profiled?

I’ve heard of false arrests because of it, but it seems like those issues while be resolved with time.

Could not agree more.
