    No, there’s no security benefit to this.

    One goal of the signal foundation, has been making end-to-end encryption accessible for normal people. Keeping things simple one phone number per account is one method they used to do this. It does diminish an anonymity, it’s using phone numbers as a form of global ID. Which isn’t great.

    So people could argue, that well having multiple signal accounts on the same device aren’t against the philosophy, they’re not going to spend any engineering effort making it happen.
