and how can I end this?

Thank you

No, where can I find it?

I've had second account named Hytale a long time ago, but it changed to r_hytale and I can't remember more of that username, now is tanki online new, and I don't know how to get in that account, because the name changed. I was before singing in with Hytale, even when my name was different. Can someone answer me, what can I do? Edit: Because when I click forgot username it shows me password recovery and nothing else.
