I use my computer as an alarm clock, and despite it being summer, I still like waking up before noon, so I'm still using it. However, as my computer is around my friends quite a bit, I like to keep the "Require Password to wake from sleep" option checked. However, this seems to interfere with the function of my alarms. I've done quite a bit of Googling to find one that might work, but so far I've come up fruitless. I've tried iRooster, Awaken, Alarm Clock (and Pro), and a few dashboard widgets I don't remember the names of.

So, my question is: Is there an alarm (preferably free or in the sub-$20 range) that will work with the computer lock OR has anyone found a suitable workaround for this problem?
