Seamless Telegram Web OAuth Login

The login_url Parameter

Instead of requiring users to enter passwords or 2FA codes on your website, you can attach a login_url button in Telegram chat. When clicked, Telegram securely prompts the user and passes verified user data via GET parameters to your auth endpoint.
