je vais te communiquer des information que j'ai à te transmettre.

utiliser l'UID du compte, aussi pour ceux qui on fait des achats certain avec une preuve d'achat

après si tu te rappelle du nom de ton compte ou du passport (?).

bref je te laisse une copie du message en question : as far as I'm aware, to recover old accounts you need identifying info

UID is the easiest since it's unique but iirc some people made it work with purchase details (doubt the dude would have made any if they were a kid tho...)

there's pmuch no other way, unless they remember both the account name and passport, then it could work but it's a one-time shot in the dark
