Apparently that lasts for awhile and then you will need to log in using security questions again. Interestingly I got Dr FM to login to her account and then we set up her security questions together, so I would be able to log into her account in future but I found I can log in without using them, just normal pin. This is a different computer in a different town to her. I assumed it would be via a cookie system. Anyway presumably at some point I will need her info in order to be able to login.Since the change came in, I have logged in a few times using the "questions"; now it is no longer asking me for any supplementary login info at all, just FF#, name and PIN get me in as they did previously.
