The quick version of my question: Why does my Yahoo email readily open on most devices without prompting for the Primary Password? I'm not particularly tech savvy but I've looked and I haven't created any exceptions that would allow opening my email to be bypassed from the PP. Longer version: I use MF as my preferred browser and I have many websites bookmarked to which my passwords are autofilled. I work from home but I am my replacement at her office location. I was alarmed to find that when I brought up an MF browser on desktops at the office location, there were my bookmarks along with the ability for anyone to effortlessly login to a given website since the passwords were saved. to remedy, I tuned off Sync, but that didn't seem to solve the problem as my bookmarks were still exactly and easily accessible. Then I created a Primary Password on the two desktops at the remote office location, as well as several devices in my home. The puzzle is that Yahoo opens with no problem when I select that bookmark. I don't get prompted for the PP until I open another browser page. Also of concern: when I select a password protected bookmark, I can manually enter my login and see my sensitive account information if I just keep clicking on Cancel when the PP prompt appears. Is that because knowing the password "overwrites" the security of the PP?
