Privacy & Security

Everything you post on social media lives there forever — even if you delete it. Just ask anyone that's ever posted something stupid. Instagram does not provide built-in tools to save or download images and videos from other users, but there are workarounds. Third-party tools make saving other people's photos and videos easy, and there are always screenshots.

In the US, law enforcement officials can make you unlock your smartphone with a fingerprint, but they can't force you to input a password or PIN, which would violate your Fifth Amendment rights. To help you from ever being in a scenario where you're forced to put your finger on the Touch ID sensor, Apple has a built-in way for you to disable biometrics on your locked or unlocked iPhone in mere seconds.

Every single photo you take carries with it a considerable amount of seemingly "invisible" yet important information known as metadata. Although metadata is usually helpful to sort your photographs by location and date, that same information could potentially be used against you, especially if the pictures are taken during a precarious situation.

With protests springing up across America, there's a chance you may have your first interaction with law enforcement. Many demonstrators will have their phones in-hand to film the action, which, sadly, could prompt an officer to demand the device and any self-incriminating data it may contain. Before this happens, you should know there are tools at your disposal to protect your data in such situations.

You may be familiar with image-based or audio-based steganography, the art of hiding messages or code inside of pictures, but that's not the only way to conceal secret communications. With zero-width characters, we can use text-based steganography to stash hidden information inside of plain text, and we can even figure out who's leaking documents online.

It's open season on Zoom, the video conferencing platform that has grown in popularity during the COVID-19 pandemic but has come under fire due to privacy issues.

While Apple has moved on from Touch ID to Face ID in newer iPhone models, there are still plenty of iPhones with fingerprint sensors — in fact, Apple's second-generation iPhone SE is the first new Touch ID iPhone in three years. With Touch ID, you can register up to five fingerprints, but it doesn't stop there. Using a little-known trick, you can sneak another five fingerprints in there for a total of ten.

Starting with Android 9 and 10, Google made privacy and security the main priorities for Android updates. Both versions brought numerous changes to help erase the notion that Android isn't safe, but Android 11 might even have them beat.

When it comes to cybersecurity, one layer isn't enough. A complex password (or one created with a password manager) does a good job of protecting your data, but it can still be cracked. Two-factor authentication strengthens this by adding a second layer of security, giving you even more protection against online threats.

Stumbling upon a specifically tailored advertisement on your iPhone can be a bit disconcerting. But that's what happens when you let advertisers track your data. Some of you may appreciate more relevant ads in apps, but the rest of you might consider it a straight-up privacy invasion.

There have been concerns with how much personal information Google tracks and all the things they know about us. Of course, that's what makes Google services so useful, they can use that information to cater to each of us individually. So yes, it serves a purpose, but it's not great for personal data security.

WhatsApp is the go-to messaging app for millions worldwide and its easy to see why. The app can be considered the Swiss Army Knife of texting thanks to numerous features like Group Chats and Status Stories, in addition to striking a great balance between ease of access and overall security.

Smartphones are inherently bad for privacy. You've basically got a tracking device in your pocket, pinging off cell towers and locking onto GPS satellites. All the while, tracking cookies, advertising IDs, and usage stats follow you around the internet.

Smartphones are more like computers than actual telephones. Unfortunately, thieves, hackers, and other bad actors know this and are always looking to make money off your personal data. Thankfully, your Galaxy S20, S20+, or S20 Ultra has tools to combat these threats — as long as you know where to look.

If you use Google Chrome on your computer, you've undoubtedly saved a ton of passwords since the browser always prompts you to. But Samsung uses their own password service on their phones by default, so you'll have to change a setting if you want to use your Chrome passwords to log into apps and sites on your Galaxy.

Thanks to backups, Signal conversations can span over multiple years and multiple phones. These archives can get rather large as you share photos, videos, and other files with friends. But between the other apps and large files on your phone, you might not be able to afford to keep all those messages.

Using a strong password is critical to the security of your online accounts. However, according to Dashlane, US users hold an average of 130 different accounts. Memorizing strong passwords for that many accounts is impractical. Fortunately, password managers solve the problem.

The bigger the group chat, the harder it is to follow. Messages start flying one after the other, and before you know it, you're hopelessly lost in the conversation. With most chat apps, there's nothing you can do, other than telling your friends to slow down a bit. But on Telegram, you can make them slow down.

Google recently released a new mesh router known as Nest Wifi. The updated and rebranded Google Wifi brought many improvements, such as faster processing power and an increased level of wireless security called WPA3. But while it's not enabled by default, you can still get the new WPA3 security on your original Google Wifi.

With all the talk about privacy concerns recently, Google's name keeps coming up because they are a very data-driven company. As an Android user, they know basically everything about you based on your device usage. That can easily scare some people off who are worried about their privacy and security. You do have some say in what personal data Google controls, but what if you want total control?

Over the years, we've seen security breach after security breach, as well as high-profile data scandals where collected personal information was misused by companies. Apple makes customer privacy a priority, so there have been few issues to worry about when it comes to its services on your iPhone. However, there are still plenty of privacy settings to explore and change, especially within Safari.

The camera system on the iPhone has never been better. Apple's iPhone 11, 11 Pro, and 11 Pro Max sport some of the best shooters on the market. But no level of quality makes up for the fact that shady apps can access your cameras for nefarious reasons. You can take control of the situation, however, and block any app you want from using your rear and front-facing cameras.

As with most social media platforms, Instagram can be a double-edged sword. On one hand, it's a great way to share and express yourself — but on the other, it can be just as effective at compromising your privacy. Thankfully, there are a few things you can do to protect yourself.

As fun as Twitter is, it can also quickly turn scary. Anonymous, aggressive, and troll accounts can attack you for your tweets and stalk your every move. While you could make your profile private and block users, there are lesser-known privacy and security features that you can switch to improve your safety online.

If you don't want to be found on Twitter, there are several ways to do that without making your account private. For instance, you can choose an obscure username, omit your real name, or pick a random avatar. But there are lesser-known features deep in your settings that can also protect your privacy online, including preventing photo tags.

As long as you're on the internet, you can be hacked. With an estimated 2.65 billion social media users, these apps are prime targets for hackers.

Here's the situation: you need Face ID or Touch ID disabled, yesterday. You don't have time to dig around in your settings, slowly working through an authentication reset. If you find yourself in a place where you think your own face or fingerprint will be used against you, use this trick to instantly protect your iPhone.

Samsung, like other OEMs, partners with third-party companies to include their apps on Galaxy devices. For example, Microsoft pays Samsung millions to pre-install certain Office apps. But one of these partners might not be on the up and up.

It seems like all tech companies want to know where we are. Even Apple and Google have been caught abusing their location access on iOS and Android. Luckily, there are apps that can trick your phone into thinking it's somewhere it's not.

In iOS 13, Apple added an important new feature to its HomeKit smart home ecosystem called HomeKit Secure Video. With it, you have a secure, private way to store and access recordings from your smart home IoT cameras.

Have you ever wondered how some people know you're online even though you swear you set the Messenger app to hide your active status? No, you're not crazy — it's an issue with two conflicting settings, and there's an easy fix.

In iOS 13, Apple introduced HomeKit Secure Video, which allows smart home devices with cameras to give iPhone users a private and secure way to store recorded videos. Plus, it has benefits such as object detection and activity notifications. Logitech is the first to add support for HomeKit Secure Video with its Circle 2 cameras, and all it takes is a quick firmware update to get started.

We've all seen the login pages that allow you to log in to third-party accounts using your credentials from Facebook, Google, or Twitter. It saves you the trouble of creating another account and remembering more passwords — but it can also become a privacy and security issue, which is why Apple created the "Sign in with Apple" feature for iOS 13.

The Pixel 4 and 4 XL are the first Android phones released in the US to support secure facial recognition. You no longer have to hate on your Apple's friends because you now have "Face ID" as well. So I assume you want to set it up right away — here's how.

If you have friends who aren't privacy-conscious, you've surely heard the old "What do I have to hide?" excuse. Despite the fact that billions of people are using the internet each day, many of them don't know the dangers that can find them. And many don't know the tools to combat them.

If you're concerned about someone accessing your OneDrive files, you may want to upgrade your protection by enabling fingerprint or Face ID unlocking. Your sensitive information deserves to be protected, and now you can do so easily. Worry no longer — if you need to let someone else use your phone, with a password-protected OneDrive, sneaky file grabbers will be out of luck.

Apps can collect a lot of data. Even if they don't have permission to access your GPS or camera, they can still read other sensors and learn a lot more than you'd think. Your gyroscope could be used as a keylogger. The light sensor could read your visited links. But if you're on Android 10, you don't need to worry about this.

If you've ever used the Find My iPhone and Find My Friends apps in iOS 12 and below, you may be surprised to hear that those apps have joined forces in iOS 13. Now, instead of two separate apps, they're combined into one convenient package. But what does that mean for you and your privacy and security?

When a photo or video is just too sensitive to leave laying around in your Photos app, you'll want to either delete it for good or hide it away in safe, secure location on your iPhone. As for the latter, Apple actually has a few tools available to make photos and videos hidden — even password-protected — on your iPhone.

"Why do I keep getting popups on my phone when I'm not even doing anything?" I see this question asked all the time. The answer? You have a shady app on your phone and it started showing full screen ads. But people either don't know this (so they don't know they just need to find and uninstall the problematic app), or if they do know it's a bad app, they don't know which app is causing it.
