>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.

>not the other way around

Exactly. I think that's important to know before people start giving out their Signal handles left and right because they think they're anonymous now.

Ah, that's what you mean. Yeah, if you want to be anonymous to Signal itself, I don't think that's possible. If you want to be anonymous to people, I think you can delete and recreate your account. I think that might do the trick.
