Telegram authentication requires you to open a chat on the phone. It's convenient to have a QR code for the case when you want to log in on the computer but have Telegram only on your phone and would be able to scan the QR instead of copy-pasting the link from the computer to the phone any other way. Originally we thought of generating QR on the client but found backend-generated QR a better alternative because we avoid adding one more JavaScript dependency to the frontend that way.
