We agree.
But there is no existing solution for using the same profile on multiple devices without compromising security more than we're comfortable with. In time, we will find a better balance for UX/security than now and then what is offered elsewhere. 🧵

Why don't we just do what Signal / WhatsApp do? They, effectively, convert each direct conversation into a group. This approach has some solvable and some unsolvable problems:
1. Adding device does not show notification to the user, and can be used as an attack vector (). This problem is solvable, and we hope to see Signal and WhatsApp solving it.eprint.iacr.org/2021/626.pdf
2. It might be possible, for a malicious contact send different messages to different devices of their contact (). We didn't validate claims in this post, and this problem, if exists, is solvable too (e.g., with Merkle DAG).scribe.rip/@TalBeerySec/h…
3. It might be possible to send messages to some devices of the contact and not to others. This is solvable for centralized providers, and not solvable for decentralized delivery.
4. You contact can see which device you send messages from (with minimal modifications of their client software). This is not solvable with the "group" design. It as not a problem for trusted contacts, can be seen as a "feature", but not acceptable for untrusted contacts.
So, we will offer a better solution in time, and in cases it does not work - you can manually create multi-device groups with trusted/frequent contacts.
