I’m still trying to figure it out, but I guess not. The only thing I’m sure about is that you will know whether the OTP code has been sent by Telegram or a P2PL relay

You can decide to send sms codes only within your country. You decide whether the tradeoff between costs, privacy and features is worth it. Sending 150 sms a month (or a magnitude more) would cost me 0 €. I find some of the premium features worth paying for. But I would never relay OTP codes for telegram

Especially since they are aiming the service to improve sign-up reliability in countries that block telegram

It’s mainly to offload the cost of sending verification codes via sms to users, which is one of the costs that Telegram wants to cut. As far as I remember, it amounts to, like, 7% of all their annual expenses (I will source this later). A couple of years ago they decided not to send sms verification codes when you sign in from a third-party app, and just send the code to active session. This sounds like recipe for moderation headaches and privacy disasters, but also good way to boost their premium metrics :)

It’s opt-in, of course

I’ve just tried to sign up from Firefox 122 and it worked. No captcha or other kinds of anti-bot puzzle to solve

So it begins
