Everything I read says Yahoo has had problems with security. If I want to want to automatically log out when I close Yahoo, that should be a option. It is not secure to walk away from my computer if anyone could open my email. I am sick of trying to read something online and Yahoo keeps interrupting with suggestions for me to view. I do not use a cell phone often and for 3 days now I have had to go looking for my cell phone before Yahoo will allow me to login
