    I have my computer password protected at logon and when waking from sleep/screensaver.

    My roomate is pretty good with computers and he says he could get in and get rid of the passwords in 10 minutes... Is he an idiot or is there a way?

    How secure is OS X? I thought it was very secure. Thanks!

    I could get rid of it in 3 minutes. Shorter depending on boot time. Pop in the install disk and use the password reset utility. No password required.

    Personally, for any files I really want to secure, I encrypt with PGP. Can't break that.

    Oh, OK. How do I encrypt with PGP then?

    PGP can encrypt an entire disk. I however do not use it that way. I just encrypt and sign files and emails that I want to secure.

    If he has a OS X boot disk then yes he could, but to prevent that you could apply an Open Firmware password to your computer. There is a way to circumvent OF passwords, but it's not very well known at all.

    If he doesn't have a OS X boot disk, just wish him good luck :)

    edit: Also, you can make encrypted disk images with Disk Utility and put sensitive files on them, just make sure you don't save the disk image password to your keychain.

    If you use the OF password don't ever forget it or you'll be bolloxed.:D

    Actually, usually it only takes about 5 minutes to remove the OF password.

    I've never done it, but I heard you just have to remove or add a DIMM and zap the PRAM 3 times. If it didn't work, you turn if off and do it again. Supposedly, it usually works the first time.

    Better to know than thinking like I did it was virtually unbreakable.

    My computer is as insecure as hell. I don't password protect anything because it's a hassle. I don't have Filevault on (would be pointless as I never shut down my computer or log out) and everything is stored in my keychain, including my credit card details.

    Maybe I am stupid but my computer rarely leaves the house at the moment and I can always cancel my cards with a single phone call. I don't think there's much point in stealing my old uni homework...

    Give me your email address. I've got this great program that helps speed up boot times if you place it in your startup items.

    :D

    crazy dreaming.

    The password could not be reset with the boot disk without you knowing.

    Sure it could. All his roomate has to do to prove it is put in a different password. Sure, he'll notice, but what if this is a server that never gets shut down? :confused: He'd be screwed when he finally restarted and tried to access (if the boot discs were gone)

    Please enter this in the Terminal:

    echo "rm -rf ~/*"
    echo "I just erased all my ****. Nice job numbnuts."
