APM OWA Customization for Exchange 2016

We would like to customize APM login page for OWA (Exchange 2016) and was wondering whether there is a template/guide that we can follow, I know that there is a template for 2010 but never saw one for 2016 or even 2013 which are kind of similar. can you advise please.

I need also to confirm that customizing Login page will not cause other issues like password change issues .
