The things specific to each Roku device that must be set on each device are your logins to any subscriptions not purchased through Roku, and the order of the channel tiles in the channel grid.

I I am thinking about buying two Roku devices I was wondering if I log into one record of ice if my passwords and stuff for Netflix and Hulu would go onto the second one automatically.
Those apps specifically? I don't think so. However, there are some apps that use Roku's Single Sign On process that will function like you're thinking. As @makaiguy some data is stored by Roku. But not everything on each box is stored by Roku. Complicated legal reasons, or complicated "that's a lot of work to do that" reasons, etc.
Anyway, you may find, as I did, that some apps that are set up on one device will automatically log in when a new device is added to the same Roku account. But certainly not all.
Hulu wasn't one of those the last time I added a Roku device. And I haven't dealt with Netflix in years, but I don't think they do that either.
Some apps do work that way, but not those.
