Will we have linux versions of Opera GX? ...and if so, how long?

I lost my password and I don't know which email I used when I signed up. It's an old account, but I'd like to reactivate it.
I know the username and certainly the email I used is still valid (I have several for work reasons).
I don't know where to get support to request a reactivation email or anything else.
Can anyone help me?
