Recently discovered this. Molly supports link with existing device just like on signal desktop. It even has benefit of getting entire chat history unlike signal desktop. Just restore the signal backup file during setup and then click link with existing device. Then scan with you primary phone. Beauty of open source. Molly: https://molly.im/
Is there any real security-minimizing reason why it’s not wanted by the official app to have multiple mobile devices linked to one Signal account? (I’m not even talking about a second phone with another SIM card, I just wanna use it on my tablet).
I would appreciate a simple/ELI5 style explanation if there is one, I don’t work in IT.
