Do I need to change the user/password to connect to different remotes from off the network?

If I am outside of my network (like via an iPad on WiFi at a coffee shop for example), if I want to connect to my remote at home and then a remote at a friend's house, do I have to logout of SmartLink to connect to the different remotes (since they have different user/passwords)?

If I use my Maestro, can it store the credentials for different sites so I do not need to login again?

I am trying to understand how manual a process using multiple remotes is. I realize that may not be everyone's use case, but my focus is on a club remote shared among multiple people but also users that may want to connect to their remote at their house (but while they are out and about).

Thanks,
