TeleIn

Overview of My Submission

I have build an authentication system where user can login in the application(android) with the help of Telegram (Bot service). In this system , any user has not to go through any hassel. Any user just need to follow the steps to login the TeleIn app

1. Go to TeleIn app's login page
2. Click Login and it will redirect to Telegram app
3. Now in Telegram , just click start
4. The TeleIn Telegram Bot will provide a link
5. Click the link and you will be redirect to the TeleIn
6. By default it'll take your Telegram name, you can change it now and Submit.

That's it. Its too simple. No OTP no email comfirmation no extra auth flow! Just simple!

Cosmos DB is the place where I store the data of user safely using the Node server.
