So far I have to create a new username/password on each instance and subscribe to all the things I want to on that new account.

Why are you needing to do that? You only need one account on one instance and you can subscribe to all the things you want on every instance (assuming that it hasn't been defederated for some reason). That way you'll only have one account with one list of subscribed communities instead of differing ones on different accounts.

I mean ideally you wouldn't need to create new accounts. You should be able to interact with instances outside of the one you signed up for.

If the issue is with different instances having different rules and defederation than you are pretty much back where you started either way even with a sort of back up subscription list

I suppose it might be useful for when an instance goes does like some with the .ml domain have.

I like the idea of packaging up a user liked that. Check out lasim for someone doing something similar.

But, you don't really need to create an account on every instance you encounter.

One account is enough if you pick a reasonably sane instance that hasn't gotten itself defederated.

From an account on one instance you can view All, subscribe to Communities on any instance, and generally just use that as your home base.

If you want a few accounts as insurance in case the instance you picked goes offline due to external factors or for whatever reason, you can use lasim to synchronize your subscriptions between instances.

This is on the line between Lemmy support and Lemmy development. Given rule #3 is about using Lemmy, please see the sidebar for support suggestions or check out development communities to discuss this further.
