I can access my webmail just fine, just given the Tiscali security flub, I would just like to change the password to my webmail, but upon reading the FAQ on "Managing your email addresses in My account from https://help2.talktalk.co.uk/managing-your-email-addresses-my-account
"I'm no longer a TalkTalk customer: Once you leave TalkTalk, your email account will remain active but you won't be able to manage it via My Account. We recommend switching to another email provider after this point. "
I was never a talktalk customer, I just signed to use the mail service more than a decade ago. Heck, I doubt if I recall any detail(s) I used when I registered back then.
Given I still have the both the introductory/welcome and Your Tiscali Account Details mails Tiscali sent me upon registering. The latter includes details I would need to access the members area. I assume the members area is now defunct and most likely the My account settings.
Then how would I change the password to my webmail?
