hey there,

Can anyone point me out where is the source code of the front end as well as the backend of the login page of phpmyadmin in the git master branch ?

The authentication plugins are here:

https://github.com/phpmyadmin/phpmyadmin/tree/master/libraries/plugins/ auth

And is the front end code for the login page present in a single file or is distributed and linked over many files?

It's in single file for every authentication method.
