New password for a Virginmedia.com email account

I managed to retrieve my "additional" mailbox and set up a new "third party" and a mail password.

I don't quite know how it happened, but something like this.

Open a "new private window" aka Incognito etc, so that I am not carrying forward any VM cookies that get in the way.

Go to mail.virginmedia.com and select the "forgot password" link, giving the VM e-mail address that I always had but lost the password.

Then I think it instructed me to provide a non VM e-mail address for that address (which of course will be different from the "primary" non VM address that relates to the actual VM account). So I gave a yahoo address i have.
Then it sends a link to the Yahoo address in an e-mail from where I click to "verify this is you".

From there I have to set a password to login to the VM account that is linked to the Yahoo account that relates to the VM address that belongs to my VM account that I access using a Gmail account that relates to my primary VM email address which is actually a ntlworld address.

After I have set that password, I can log into MYVM using the Yahoo address and finally I can change the password on the "additional" e-mail address.

With that degree of "simplicity" (??!!)) I am not surprised that the Virgin help pages make a hash of explaining it.
