Stop with the less secure access nonsense
Every time I log into my mail I get pestered to add my phone number.
This isn't going to happen. I only vaguely trust you with this email address so I'm not going to let you have my mobile number.
Please give us an option to say we understand the risks, never ask again.
I know people often say they are going to close their account, and I know you don't care but this is soo annoying that I will have to ditch yahoo for good.
