Facebook’s Messenger Kids app—the kind of app you put on your child’s device to ensure they can only talk to approved contacts—had a not-so-helpful bug that allowed strangers to interact with kids.

If you’re using an app to get food deliveries, your tip might be going right into the bank account of the company the deliverer works for, not the person’s pockets.

Being able to turn your smartphone into a miniature access point that can give other devices an internet connection—like your laptop—is one of the best features ever. It’s saved my bacon plenty of times, those rarer moments when I need to use my laptop for something (like editing a Lifehacker post), but can’t access…

I used to save my data on services forever—in case I ever needed to take a trip down memory lane—but I’ve recently found lots of relief and joy in purging my Twitter account of old tweets.

The good news? A recent phishing attempt hit Discord and only ensnared a small batch of users—around 2,500 in all. The bad news? There’s no easy tool to tell if you’re on that list, so you might as well take a moment to reset your password on the service right now. More important, it’s time to stop being lazy and…

One of the best tips I can give any flyer who doesn’t want to pay stupid fees for the slight extra legroom of “premium” seating is this: check your seat assignment constantly.

Comcast’s mobile carrier, Xfinity Mobile, is finally opening its doors to Android devices—but not all Android devices.

If you have an Android phone you aren’t using anymore, don’t let it collect dust in a drawer. Donate it to the Duke Lemur Center, which will be more than happy to use it to learn more about lemurs’ ability to perceive colors.

We’re going old-school with this week’s Tech 911 column—Lifehacker’s weekly Q&A where we solve your quirky technological issues. While plenty of people now use their smartphones as their default camera of choice, some still enjoy a trusty point-and-shoot. And the elite among you might even pull out something called …

Paying for wifi on an airplane? You must be made of gold, because there’s no way I’m ever going to plunk down $10—or more—for a mere 30 minutes of internet time. At least, that’s what Gogo was charging on my recent Alaska Airlines trip. But thanks to a few clever workarounds (if I do say so myself), I was able to get…

You sit down at the airport, ready for (or relaxing during) a big day of travel. You have the perfect spot, closer to a power outlet than to annoying people. And right when you open your laptop, you realize... you have no idea how to get on the nearest wifi, or even what its password is.

You might be paying your ISP for a certain service tier, but that doesn’t mean that you’re getting those speeds both ways—the fine print will likely indicate that your upload speeds are much, much slower than your download speeds.

I have one of those bougie credit cards that comes with airport lounge access—via Priority Pass—and I always wondered what the point was. Sure, you can get a few free snacks and a decent place to sit, but it’s not like the lounge is passing out free Cinnabons and rum-and-cokes to all attendees.

Amazon Prime Day is here. If you’re not boycotting the site, and are instead planning a big shopping frenzy, there’s a good chance you’ll be able to find some kind of discount for lots of items on your must-have list.

Little is more miserable than getting off a six-hour flight; spending an extra hour in the airport to get off the plane, get all your baggage, and huff it over to the main transport hub; and then realizing you have no idea where you parked your car.

The great Amazon Prime Day is nearly upon us (Monday, July 15, midnight PT). Naturally, Amazon wants you to part with as much of your money as possible, but it isn’t the only one. According to a report from Wired, a big phishing scam called 16Shop is looking to sucker unwary spenders into giving up key details—their…

Welcome back to Tech 911, Lifehacker’s weekly tech-advice column that’s always looking to solve your challenges—geeky, strange, or otherwise. This week, we’re taking a look at a case of mistaken identity.

From your geeky roommates who eat up your internet connection at all hours of the night to your luddite family members, nearly everyone knows what BitTorrent is nowadays. They might not be able to describe how it works, or even legal ways they can use it, but they know it exists. (If you’re a little geekier, you…

It looks like New Orleans is going to take a shot from a potential Category 1 hurricane by Saturday. Half my family is from New Orleans, and I’m confident in saying that none of us would be nervous about a Cat 1. However, it’s not so much the winds that are the problem with maybe-Hurricane Barry; it’s the water.

One of the very first things I do when I’m faced with a fresh operating system is to fire up its default browser—the meh Edge or Safari—and head straight to Ninite (Windows) or macapps.link (Mac). Both sites allow you to pick and choose apps you’d like to install on your new system. Once you’ve finalized your list,…
