Moving host

Hi

I want to move host but i’m worried what will happen because i access via some sort of pluggin via my host.

My current host is Ipage (i do not recommend them). I chose them because they offered free domain name and wp access.

I’m worried because I log in to my dashboard via a very generic username. I am worried that this is some sort of access through my host, so that when i move host I won’t be able to edit the site because i won’t be using that host anymore (if you get me).

Am i going to be able to move host and still access the site i have already created?
