I mistakenly chose the option for my mobile phone to remember my log-in and password for my Hotmail account so I didn't have to type in the details each time I wanted to access it.  I want to cancel the instruction and go back to entering my log-in details and password each time I want to use my Hotmail account as I feel it's more secure that way.  There don't seem to be any options for doing this anywhere on the site - any suggestions as to how I can do this?
