How to login to Opensubtitles on Kodi?

Hi,
When i was using 16.0 and was using Opensubtitles i kept getting an error message that i needed
to get an Opensubtitles account. So, i got an Opensubtitles account but then i uograded to 17.0 and now i do not see where on Kodi i can log into myOpensubtitles account. How do i log into my Opensubtitles account on Kodi?

Also, is it secure to login to an account you use elsewhere on Kodi? It was not a secure connection when i registered for Kodi forums.
