Indeed. It's stupid. And it's very much scaring off their less technical users. My aunt is nearly 80, she's been using signal for years, and the other day she sent me a very confused message about the PIN. She doesn't understand why it's suddenly there, and she doesn't want it there. Neither do I. And there's no way to turn it off? I won't be recommending signal anymore. It used to be a mostly secure drop-in replacement for the default SMS app, and it was truly stellar at that. But if it's going to become a pain to use, what's the point?
