This service is free for both users and developers. Why? We don't really know.
Login and auth pages are optimized for all screen sizes and resolution.
Telegram Passport implements generic OAuth2 protocol and follows the RFC standarts.
Everyone can participate and translate Telegram Passport on any language.
We don't use our bot to send any messages, except for the login status.
We have libraries for that! All of them are open-sourced and available on GitHub.
Telegram Passport is a bridge between your website and Telegram Messenger. Users can sign up and log in to your service with one click.
No, we are not affiliated with Telegram and Telegram team. But we use an official bot API and don't violate Terms of Service or any other rules.
First, you have to login and create an application. Then you have two ways: use one of our libraries or implement the OAuth2 authtorization manually.
Literally anywhere. We follow the RFC standarts, so you can implement the telegram login on any programming language in any app with internet access.
This service is not intended to gain any profit, even with ads. We may add some premium features in the future, but not in the near future.
