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?

Accounts reside on the instance they belong to. Same way you can’t use your gmail account to access your outlook account.

Unfortunately, this doesn’t work, but Pixelfed just added a “log in with Mastodon” option yesterday. It’s not impossible that it’ll come to lemmy one day.

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.

Lemmy instances are federated with each other, allowing a user on a given instance to participate in a “community” on another Lemmy instance without having to create an account on the other instance;[4] and with other instances in the Fediverse that use different software. ActivityPub is the protocol used to allow Lemmy instances to operate as a federated social network. It allows users to interact with compatible platforms including Mastodon and PeerTube.[15]

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.
