Hello I am looking to self host my own pixelfed account just because I like self hosting and like sharing pics.

I saw there is a sign in with mastodon option on the pixelfed site and was curious if I host a mastodon instance instead, could I then use pixelfed with the same account?

I have a lemmy, mastodon, and pixelfed account right now and from doing a few experiments it seems mastodon has the best federation with both pixelfed and lemmy as far as commenting back and forth so it would be pretty neat to use a mastodon instance if that is possible
