As someone who isn’t tech savvy I only joined the fediverse when I had no other choice when Apollo shutdown (except of course going back to Reddit)

Heck when I heard talks of lemmy hearing the word servers was enough to spook me out of joining until last minute

I had a point in here somewhere but I’m so tired i lost it so feel free use your imagination

Try the recovery codes would be what I’d do

Maybe try the I no longer have access to the “I no longer have access” button, unless the only option there related to point 1

If all else fails you could contact customer support
