Yeah, so they will indeed be able to link my phone number to my username, even if the number is set to "hidden".
This sounds unfortunate, but I guess there's no way around this as long as Signal insist on keeping phone numbers as primary identifier.
I don't think this is the case.
If you set your privacy to nobody and someone saves your phone number, to them it will appear that you do not have a signal account, even if they start chatting with you via your handle.
How will they be able to link your phone number to your username? They can't do anything with your number unless you choose to.
>How will they be able to link...
By "link" I mean they immediately know what person the username belongs to iff they already had that person's phone number because the chat that is initialized after they scan the QR code is just the old chat being continued.
But if they have my number, why would I be worried that they know my username? The username is there so I can avoid sharing my number, not the other way around.
