Yahoo! / BT data hack

Manxman_in_exile

I'd be grateful for any advice as to whether I need to do anything other than change my BT email account password after last week's news about the Yahoo! data hack?


I understand names, BT email addresses, 'phone numbers and email passwords were stolen.


We don't do internet banking and we're very cautious about ever putting any sensitive financial information or passwords into emails so I'm hoping a change of email password is all that would be necessary.


Obviously we do buy things over the internet (with associated web-site and payment card passwords) but only through https: websites so I'm assuming they don't need changing just for this data hack.


Thanks
