I thought one of the advantages of the Fediverse was to have one account but access to many services. Is this possible just not common? I already have a Lemmy account and Mastodon and I didn’t want to start making more just to try out the other services.
Lemmy mostly federates with Lemmy, but everything else out there (PeerTube, PixelFed, etc) has been developed to work well with Mastodon (sometimes to the Fediverse’s detriment), so your Mastodon account should be all you need.
And Mbin and Piefed!
From other replies it sounds like this isn’t guaranteed. I tried logging into pixelfed using my Mastodon info and it didn’t work (stopped me as soon as I gave the instance).
