I think I lost my WordPress.org account as I cannot get password reset or account access with my personal email id.
I am wordpress user since 2006 but now I cannot access my account.
Do their any specific way to retrieve WordPress password?.
You would need to talk to the folks at WordPress.org about that one, they would control the userid. I am not aware of any recent changes to their system, but best to post to their support forums here: WordPress.org Forums
