Do to have any kind of DATA PROTECTION ??
When you send me an email telling me I have logged in via the web, why do you list my entire phone number and recovery email address?
IF someone else had "hacked" my Yahoo email, they would know ALL my personal details! Have you ever thought of that ??
Also you first text me a code to login, so what is the point of your email to me with all the details and IP etc. etc. ???
