If you've ever used Google to search for, ahem, "adult" content, you're aware of the site's SafeSearch feature. It filters out questionable content, to the delight of parents and the dismay of porn-seekers. Now there's a new "lock" function for SafeSearch, which keeps your account's settings locked in strict filtering mode until you enter a password and change them. The obvious use here is for parents looking to keep risque material out of view of their kids, but I can also see it being handy to prevent embarrassing search results from accidentally popping up at work.

When SafeSearch is locked, you'll see four extremely conspicuous, very large colored balls in the top right corner of your search results. Google says this is so parents and teachers can tell from across the room whether the lock is still in place, and come over to reset it if it's not. It even works across Google's various languages, so clever kids can't get around it that way. Could they thwart SafeSearch in an even more obvious way, though, by simply logging out of Google? I guess that's where keeping a close eye on the giant colored balls comes in.

If you're confused about how to go about turning the lock on, the very clear video instructions in Google's official blog post will shed some light.
