Blocking access to distracting websites on Chrome can help reduce distractions. Blocking inappropriate websites on Chrome can also keep children safe online. One way to block websites on Chrome is using a website-blocking extension. However, you may not like it. Uninstalling extension (which can be easily done by anyone with access to the browser) will unblock the websites. You may be looking for a more reliable way that doesn’t involve an extension.
This article shows you how to block websites on Chrome desktop and mobile without using an extension.

Now these websites are blocked on Chrome (and other supported browsers), including in the incognito browsing mode. When you or someone else tries to open a blocked site on Chrome, it won’t open, and a message will show up saying that it’s blocked.
There are a few ways to unblock a website, such as removing the website from the block list or quitting AppCrypt. However, any of these ways requires the password. So the blocking is hard to bypass.
Tips
By default, all websites on the block list will be blocked on Chrome all the time, as long as AppCrypt is running. But the custom schedule feature allows you to schedule the blocking of a specific site, e.g. blocking youtube.com from 9:00 to 12:00 and 14:00 to 17:00 on workdays.
It’s recommended to select the Launch at system startup checkbox in Preferences.
With the allowlist feature, you can block access to all websites except the ones you allow.
Note: AppCrypt is also available for Windows. You can give it a try if you are interested.
Here’s a scenario. Your son needed to use your computer and Chrome for homework, and you allowed it. However, he ended up spending hours on YouTube when not supervised.
To prevent things like this from happening, you can use an app called FocalFilter. With FocalFilter, you can block unwanted websites temporarily for a certain amount of time, such as one hour. It’s easy to add websites to the block list and set up a blocking session.
1. Download and install FocalFilter. Open it.
2. Click Edit My Site List.
3. In the dialog that appears, enter the unwanted websites one by one as instructed. Click Save.
4. Click the Block for dropdown menu and then choose an amount of time. Note that you can only choose from the given options, which range from 5 minutes to 12 hours.
5. Click Block My Site List. And a blocking session will start immediately.
During this session, the websites you’ve specified will be blocked on Chrome browser. In addition, you can’t edit the FocalFilter settings, which prevents the blocking from being bypassed. However, restarting the computer will remove the blocking session.
When the time is up, websites will be automatically unblocked and stay accessible until you start a blocking session again.

In addition to the five methods talked about above, there are a few other ways, which, however, require you to change Internet or computer settings. If you are not tech savvy or not confident with such methods, you can ignore them. One method is to change the settings on a router that has a parental controls feature or web filtering feature.
1. Access the settings of the Wi-Fi router in your home or office.
2. In settings, find a feature named Block Sites or Parental Controls or alike. If you can’t find it in basic settings, try the advanced settings.
3. There should be an option for you to add websites to block. Some routers also let users block websites by category.
4. Add website URLs and save your settings.
This should block the added websites on all browsers including Google Chrome on all or selected devices connected to this particular network. Here are more details of this method.
The hosts file on your computer is an operating system file. It’s possible to limit access to websites by modifying this file. With this method, the blocking takes place at the device level. In other words, all web browsers (e.g. Google Chrome) installed on your computer will prevent the prohibited websites from loading. You can follow the detailed steps below to edit the hosts file on Windows.
Note: With this method, the blocking won’t work if a VPN is used.
1. Type NotePad in the Windows search box.
2. Right click on NotePad and select the option says Run as administrator.
3. Click on File > Open. Navigate to the hosts file. On a Windows PC, it is normally located in c:\Windows\System32\Drivers\etc\hosts.
4. Change the file type from Text Document to All Files on the bottom right.
5. Open the hosts file.
6. Scroll down to the last line. Type the specific website name and then type 127.0.0.1 before the name.
For example, if you want to block Facebook on Chrome, type the following text.
127.0.0.1 facebook.com
127.0.0.1 www.facebook.com
Now Facebook is blocked on Chrome. If you no longer want to block the site, go back to hosts file and delete those texts.
On a Mac, the hosts file is located in /private/etc/hosts. It can be opened and modified through Terminal.
