So recently, I got back into Destiny 2 with the last time I've played being maybe 5 years ago? I started back on my PlayStation and wanted to set up a cross-save on my Steam account, but when I went to authenticate, I saw I had to authenticate my old Xbox account that I originally started playing on. But here's the thing, it's been years since I played on that account and I've lost the email and password. I don't even know if the account is still active anymore! But I can't continue with the cross-save unless I can authenticate my old Xbox account(which I can't do). So what can I do? Or what should I do?
