List the video as Private: When you’ve uploaded the video listing the video as private, only users you’ve shared the video with can access your video. The video uploader has to add each authorized user manually for each video. However once permission is granted, the user can download the video using youtube-dl (either through terminal on Linux or through their .exe program on Windows)

Totally free, 5KPlayer from DearMob is a media-playing utility that is a lot more than a downloader—but it's got a heck of a downloader integrated. Promising no viruses, ads, or plug-in requirements is a good start. It is, sadly, one of the few I tested that asks for a registration of your name and email—you have to do that to get the full download function across 300+ sites. You may still use it if you don't register; I didn't and was able to download 4K vids from YouTube.
SaveFrom.net has made a name for itself over the last few years. It can do web-based downloads, but also provides software to install and a browser extension, which it pushes. It doesn't support 4K, but few helper sites do—going to a 1,440MB WebM file is an option, but it doesn't come with audio—the only format that does is 720p MP4s. Nor can you use SaveFrom.net to make an MP3. Of course, those options are in the downloadable software.
Using a strong password is a good way to protect your YouTube channel and Google account, but it's often not enough. The best way to secure your YouTube and Google account from hackers is to use Google's 2-Step Verification, which utilizes something you know (your password) and something you have (your phone). To login to your account, you'll need to enter both your password and a temporary code that Google sends you via text message or voice call on the phone. I highly recommend you enable 2-Step Verification for your Google account. Here's a step-by-step tutorial on how to enable and setup 2-Step Verification on your Google account and YouTube channel.
Step#4. Click on Sign-in & Security at the left-hand side. It will allow you t protect your account via password. You can also add a second layer of protection with 2-step verification, which sends a single-use code to your phone for you to enter when you sign in. So even if somebody manages to steal your password, it is not enough to get into your account. To change this setting, you will need to confirm your password. Now click on 2-Step Verification to continue this process.
Not to be confused with the unrelated "pro" above, Video DownloadHelper supports a huge number of sites—even those for adults. You'll know a video is downloadable when the icon for the extension animates when you're on the webpage. Video DownloadHelper for Chrome has stopped working with YouTube—so it could get placement in the Chrome Web Store. You can get around that by using the Video DownloadHelper extension for Firefox. The developer has a Kiva initiative page, where it prefers you donate funds to those in need, which has raised over $137,700.
That said, with Android it is possible to install apps without going through Google. The latest is InsTube – Free Video and Music Downloader just for Android—you can only get it at InsTube's site. You download the APK (Android application package) file to sideload on an Android device. Find it in your device's downloads and click it to install. (You may have to go into your security settings and enable "Unknown sources.") There is a similar side-load app from YTD.
