Telegram Login for Websites
EDIT: For clarity, the comment below has nothing to do with Telegram Login, but Telegram itself.Telegram gets a lot of hate on HN, but I have to say that of all large messaging apps Telegram has by far the best UX. That said, I can see it slowly turning into a walled garden. For example, in public channels (distinct from groups, they're broadcast only) it should be possible to link to their content from the outside. Instead if you try that they force you to download the app to see the content. EDIT2: As someone noted you can link each individual post on a channel, but you can't see and scroll through a list of posts as you can from inside the app.I wish we had a messaging app with a market as large as WhatsApp's, UX as good as Telegram, security as good as Signal, run by an organization like Mozilla.
