Block a whole video from being viewed. As a copyright owner, you have the ability to block offending videos in specific countries or worldwide. Keep in mind that a global ban can affect the account standing of the offender, and limit that person's access to certain YouTube features. If you don't want your videos shared for any reason, this is a viable option.
For this software, you just need to copy the YouTube link and paste it directly into the box that’s labeled for the link. Then you get to choose the format that you want to download it into. You’re going to need to download their specific software in order to be able to download, but then you just have to click to download, and you’re all set. It really is just that easy. You can even tell it to download multiple URLs at the same time, so you can fill in everything you want to download and tell it to start while you head off to do other things.
Having a strong password is important, too. Make sure to use a mix of numbers, punctuation, and letters in both uppercase and lowercase—or a nice, long passphrase. Don’t use the same password (or even a similar one) for multiple accounts, either. Ideally, you should also change your password every few months to stay on the safe side, and invest in a good password manager to keep yourself as secure as possible.
