Can't you log in to Jerboa using a Mastodon account and log in using a Mastodon app like Moshidon to log in to lemmy? How would that work?

The fedi community and app remains confusing to me. I don't know if they're separate federated communities or linked ones and if it's linked if they are seamless. I don't know how many levels of complexity I haven't even considered. Maybe you can only log in through Jerboa sometimes because I can't with my account.
