>Starting a Secret Chat takes one more tap than starting a normal chat.

Hmm, the article says this:

>As John Hopkins security researcher Matthew Green pointed out in his blog on the subject, it’s also a pain in the ass to activate. “The button that activates Telegram’s encryption feature is not visible from the main conversation pane, or from the home screen. To find it in the iOS app, I had to click at least four times—once to access the user’s profile, once to make a hidden menu pop up showing me the options, and a final time to ‘confirm’ that I wanted to use encryption. And even after this, I was not able to actually have an encrypted conversation, since Secret Chats only works if your conversation partner happens to be online when you do this,” Green said.
