I'm not sure how the account stuff works, I never used it. I just jumped straight to using my node. When doing it this way, you don't interact with their servers at all afaik
Yeah I just use one of the web UIs to do that personally. Only reason I'd wanna hook the two up is for the LN address. But I like how I got things setup now tbh, it's good psychologically to have separate spending and hodling wallets even putting the OPSEC and privacy element aside.
