I've tried to log into Lemmy through multiple apps using my Mastodon username and instance, but I get errors.
I thought federated accounts were supposed to be usable across applications.
Am I misunderstanding?

There is a misunderstanding here. The fediverse can communicate with each other, but you can't sign in with one anywhere. Consider it like an email. You can't use a Yahoo email to sign into a Gmail account, but you can send emails to anyone, regardless of sharing the same @.
Got it, but I figured if I'm trying to log into the application, the credentials from my Mastodon account would be authenticated against my instance there.
Like having a email client on your computer. You should be able to authenticate against your Yahoo, Outlook, or Google.
I thought federated accounts would utilize the same authentication regardless of platform because they use the ActivityPub protocol. Maybe I need to learn more about it. Based on the information about that page it looks like you can auth into Pixelfed and PeerTube using your Mastodon credentials.
I would love it if eventually there could be SSO across Federated platforms such as Lemmy.
Additionally, from the Lemmy wiki page it says it is compatible with Mastodon and PeerTube. I guess I would like to understand how they are compatible.
Yeah, I get you. But unfortunately no. They don't use the same authentication, they just connect information on the other end. It's not like the sites that allow you to sign in by using another account. You sign in Mastodon with a Mastodon account an Lemmy through Lemmy. I can't use my Kbin account to sign into either of those--I just have a separate Mastodon account.
Mastodon users can comment on a thread
Can you point to something that explains how?
Hey, so here's how it works in theory.
On mastodon, Lemmy communities (not sure about Kbin magazines) show up as groups. But you have to replace the ! in their address with a @ to find them.
For example I can search for the Star Trek community (!startrek@startrek.website ) on Mastodon by searching for
@startrek@startrek.websiteand follow it like so:New posts and comments will then show up in my Mastodon feed as boosts. I can reply to them and it'll appear on the Lemmy side too.
You can even make your own Lemmy posts from Mastodon, the first line of your toot will become the post title and the rest will be the body, you just need to tag the "group" in there somewhere.
Where it gets complicated and my knowledge falls down is that it seems like you can't always find every community by searching like the above example, and I'm not sure why. For example I just tried
@meta@lemm.eeand had no luck. BUT some that I tried to find yesterday to no avail are now showing up this morning, so maybe there's just a delay in them getting indexed the first time you search for them 🤷♀️Awesome. Looks like I'm able to find the communities but none of the old posts show.
Looking forward to see how this goes with new posts!
Thanks for explaining!
I'm not on mastadon, sorry
