How to log in FROM mobile?

Hi,
How to use this plugin to log in to your site from the mobile phone?

The only way i found is to open google authenticator, copy the code to the clipboard, then rush to the browser again and paste the code.

this is a very primitive way.
Clef has the ability to log in to sites when you are on a mobile phone, without doing a copy and paste like this.

any help, please?
thanks
