Help. Accidentally enabled 2FA and now I was signed out and I can't sign in again

Writing this from LemmyWorld because I can't access my lemmy.ml account.

I enabled 2FA and I was told to go down for instructions, yet no instructions were down the page. Days later I was signed out and now I can't log in because it asks for a non-existant 2FA code. How do I sign in? Thanks
