Double Check is a easy to use service that enables multi factor API for your applications using just a API.
Your application users just need to interact with the Telegram Bot in order to receive the access tokens.
To be defined. It would be probaly a Docker container :)
You can contribute by testing the application, opening issues about new features or bugs.
You can also fork the project, grab a issue and open a pull request to solve it.
