1. I understand that the passwords are stored nowhere but since the account info/settings are stored in the profile directory on my computer, isn't some security compromised?
Of course... there is no such thing as a completely secure computer, unless it is unplugged, locked in an impenetrable titanium safe, and dropped to the bottom of the Challenger Deep in the Marianas Trench.
2. I have offline applications (like MS Onenote) that can be password protected. Is it possible to use PM for these programs? Is this what the desktop version is for?
Yep... I use the Firefox extension to 'store' passwords for all kinds of things that aren't available online...
3. If I am away from my computer and using someone else's computer, I will still need my passwords and to access my settings. How is this possible? With the online version?
That would be the only way...
I keep mine on a copy of Portable Firefox on a usb thumbdrive for just that scenario...
4. If i am using the browser version and the online version and the desktop version, and creating new passwords from all three, are all settings saved in same RDF file? How is this coordinated?
Right now it isn't...
There is a Feature Request for syncing the file with an online copy, but, like Foxmarks syncs your bookmarks, but it hasn't been implemented, and I have no idea where that might fall in Erics Honey-Do list...
5. I understand that there is no automatic syncing system. This needs to be manually done.
From the info I read, I would want to have a "master" copy on one computer and "slave" versions on other computers.
Would I then use import/export function or copy/paste the RDF file into profile directory?
Ok, I don't know why you numbered these separately, since this is basically a continuation of question 4...
Right now there is no way to 'merge' two different RDF files, short of manually copy/pasting the raw RDF file, and I wouldn't want to try to do that unless it was an emergency.
6. Where else could RDF file be saved? In my Gmail Gspace? of DigitalBucket? I would then be able to access the settings info anywhere but would that comprise security?
All I can recommend right now is a USB thumbdrive.
