For additional security, you can require a time-based authentication token as well as a password to log into your Linux PC. This solution uses Google Authenticator and other TOTP apps.
Linux newbies have probably heard a lot about Ubuntu, but it isn’t the only Linux distribution. In fact, Ubuntu’s standard Unity desktop is still controversial among long-time Linux users today.
We’ve been banging on about the horrific and broken Windows software ecosystem for a long time now. Rather than installing applications from Download.com and every other freeware site, you should just switch to Linux if you want to download freeware safely.
Windows, Mac OS X, and most Linux desktops have built-in tools for quickly renaming multiple files. Use a batch-rename tool rather than fixing them one by one.
We were setting up a new Minecraft server at HTG headquarters to play the awesome Captive Minecraft survival mode game (which uses vanilla Minecraft, no mods required), when we realized we didn’t have an article about how to find your saved games folder.
Wouldn’t it be nice to be able to try a new version of Ubuntu while knowing you can return to the previous version if you don’t like it? We’ll show you a tool that allows you to take a snapshot of your system at any time.
If you need to reinstall Ubuntu or if you just want to install a new version from scratch, wouldn’t it be useful to have an easy way to reinstall all your apps and settings? You can easily accomplish this using a free tool called Aptik.
If you have ever received a message that your new password is too similar to your old one, then you may be curious as to how your Linux system ‘knows’ they are too much alike. Today’s SuperUser Q&A post provides a peek behind the ‘magic curtain’ at what is going on for a curious reader.
We’ve long railed against registry cleaners and system tuners as useless products that waste your money, but how do you go about cleaning up after uninstalling shady freeware? Answer: You don’t. You avoid installing nonsense on your PC to begin with by testing everything in a virtual machine first. Snapshots just make it easier.
If you’re using Linux as your desktop operating system, you probably are very aware of what version you are running, but what if you need to connect to somebody’s server and do some work? It’s really useful to know exactly what you are dealing with, and luckily it’s also pretty easy.
Most people use their operating system’s included file manager, but many geeks prefer third-party file managers. After all, Windows Explorer doesn’t offer tabs, a dual-pane interface, batch file-renaming tools, and more advanced features.
Screenshots are great, but sometimes you need to create a video recording to really get your point across. You can record your computer’s desktop, your smartphone’s screen, or your tablet’s display.
Animations on a desktop PC, smartphone, or tablet are nice — the first few times. Eventually, you just wish they would hurry up and stop wasting your time.

There’s nothing more tedious as a system administrator than running security updates on a dozen servers every single day. Luckily Ubuntu will let you automate stable security updates so you’re never at risk.
Amazon Instant Video uses the Flash plug-in, so you might imagine that it would “just work” with Flash on Linux. You’d be wrong, but you can get Amazon Instant Video to work with minimal tweaking.
A “text expander” autocorrects short combination of characters you type to longer phrases. They can be used anywhere in any operating system. For example, you could type “bbl” and have this always automatically expand to “I’ll be back later.”
You’ve set up the programs you need. Your windows are arranged just right. Then, something else demands your attention and you have to shut down. No worries. You can have Ubuntu remember all your running applications and restore them the next time you log in.
Chromebooks are supposed to have amazing, all-day battery life — but not all of them do. Follow these tips to squeeze more battery life out of your Chromebook.
TrueCrypt’s dramatic shutdown in May, 2014 left everyone shocked. TrueCrypt was the go-to recommendation for full-disk encryption software, and the developers suddenly said the code was “not secure” and halted development.

If you’ve tried to install Google Chrome in Ubuntu Linux, you may have noticed that it’s not available in the Ubuntu Software Center. However, it’s easy to download a package file for Google Chrome and install it on your system, and we’ll show you how.
