From now on, the adult websites will be blocked permanently on Google Chrome and other browsers. If your kids try to access the blocked sites, they won’t be able to open the sites on the browsers. If they try to bypass the blocking by quitting AppCrypt, they won’t succeed because it requires the password to quit. To block yourself from adult content, you can ask someone else (such as a family member or a friend) to set the password.

Tip: There are millions of adult websites. Is it possible to block all adult websites? Yes, there is actually a solution. Enable the Block all websites option. Go to Exceptions. Under the Always Allow tab, add the websites you need. This way, Google Chrome will be prevented from opening all websites except the allowed ones.

Note: AppCrypt is currently only available for Mac computers and will soon be available for Windows PC.

Method 2. Use a porn blocker extension

Available for the Google Chrome browser on Windows PC, Mac and Chromebook, some Chrome extensions (such as Netfencer Porn Block) are dedicated to blocking adult content. Some Chrome extensions (such as BlockSite) can help you block any unwanted websites, including inappropriate ones. They are easy to access and use.

However, there is a big disadvantage. Anyone can effortlessly remove an extension from Chrome. That being said, many people still think that such extensions can help them block porn on Chrome.

1. Open the Chrome Web Store.

2. Install an extension called Netfencer Porn Block.

3. Click the extension’s icon in Chrome’s toolbar and then click the Settings icon.

4. In the Blocked Sites section, add specific adult websites to block.

In addition, it will detect the words you are searching on a search engine and detect the title and content of the website or page you are opening. If the search, website or page contains a word that you add, the blocking will start immediately.

An extension called BlockAge is also worth checking out.

Method 3. Edit the hosts file

The hosts file on your Windows PC or Mac is a system file. It’s a plain text file and can be edited. By editing it in a certain way, you can block adult websites on Chrome and any other browsers. If you feel comfortable or confident using the command line, you can use this method.

The process of editing Windows’ hosts file to block adult websites is a little different from that on a Mac. Below are only the brief steps.

1. On your Windows or Mac computer, open the hosts file using Notepad or Terminal.

2. In a new line, type “” and then type the domain name of an adult site without typing “www”.
