Authentication and Single Sigon - Integrating Seahorse in another app

[FJAVEED]

Sorry if this is not the relevant forum but I cannot find much help. I want to integrate seahorse in another web app and want to implement single sign on ? What are the possibilities ?
Also when I install it on linux through docker then how can I change the HTML files (mainly login page) of seahorse. Any help ?

seahorse login is based on cloudfoundry/uaa() .seahorse proxy is controlling the authentication
