No, no, no. I have been toying my own Matrix instance and I registered 2 users that I played with, exchanging pictures and messages. There were some glitches in the UI that insiste on flagging some sessions as insecure even though I verified every session. Sometimes it got resolved all on its own, sometimes it stayed like that.
