How to block access to adult sites from PCs, Macs, smartphones and tablets

Simple ways to activate the blocking of adult sites (of all types and not recommended for children and minors) on PCs and smartphones.

Block sites
A minor with unlimited access to the Internet is not aware of the risks he runs, since there is a good portion of sites not suitable for his tender age that he can visit even by mistake, perhaps by clicking on a banner or a link on a harmless page. or on a page designed for children.
To avoid this danger we can equip the PCs and mobile devices that children use (smartphones and tablets) for block access to adult sites, so you don’t have to constantly check what they visit or where they click.
Obviously these programs and apps do not completely replace our responsibilities as parents: we will always have to check that unsuitable sites are not opened or that the blocks set are not deactivated by mistake.READ ALSO: How to block a site from a router, PC and smartphone

How to block access to adult sites from PC

If we want to block access to adult sites on a Windows 10 computer, we can set the block directly within the browser, by installing a dedicated extension.

The best extension we can try is without a doubt Adult Blocker, available as an extension for Google Chrome.

Using this extension we can effectively block all adult sites, magic sites, betting sites, and other sites dedicated to activities designed for adults and add if necessary also other sites that we do not want to be visited (for example social networks), via blacklist.
If, on the other hand, we want to pass some sites we can have the white list, where to insert the sites to be authorized.
Another very interesting function is the possibility of blocking specific keywords or phrases typed in the address bar or in any search engine: we can thus make the filter very effective even if the site is not yet present in the embedded list.
The extension is really effective in blocking sites and, if your child has strong computer skills, we can set a password to apply the changes to the extension, as well as hide the icon and make the extension operational even in incognito mode.

If we are looking for an extension available for multiple browsers, we suggest you try BlockSite, available as an extension for Google Chrome, and as an extension for Mozilla Firefox.

With this app, we will be able to set different filter levels (Adult, Social, etc.) and thus block access to the pages to minors, who will receive a nice lock screen every time they try to access a prohibited site.
Changes and removal of the app are protected by a password and the app works great even in incognito mode, so you can block adult sites in any situation.

If we do not want to install any extension on our computer we can also rely on parental filter built into Microsoft Edge, the default browser of Windows 10.

By opening your browser settings and clicking on the menu Family Safety we will be asked to create a family group and thus set the various filter levels, so as to make browsing from the Microsoft browser safe for minors.

How to block access to adult sites from Mac

If we use a Mac or a MacBook we can rely on the same extensions seen on Windows PCs, since Google Chrome, Mozilla Firefox, and the related extensions can also be installed here.

If we wish instead block access to sites from a Mac or MacBook without using extensions or dedicated apps, we can benefit from the parental controls integrated into the latest versions of the macOS operating system. To apply the blocking of sites, press the Apple symbol at the top left, click on System Settings, and let’s get to the menu Usage Time -> Content and Privacy.
Mac control

We press the button at the top right Activate, then we put the checkmark on the item Limit adult websites. To exercise an even more effective form of control we remove the checkmark from the items Explicit language in Siri and Dictionary is Search web content in Siri and configure the most restrictive filters in the other tabs present (Store, App is Other).
After configuring this block we press at the bottom left on Options and activate the voice Use Usage Time Code and choose a quick unlock code (different from the account access password).
Mac code

By doing so, no one will be able to remove the filters set without code, securing all the browsers on the Mac (Safari in the first place but also Google Chrome or others).
However, nothing prevents us from enhancing this block integrated into Apple by also adding the extension seen above, so as to obtain a truly effective blocking of access to sites that is difficult to overcome in all circumstances.

For minors, however, we recommend that you use family accounts on PCs and Macs, so as to be able to apply effective parental control; for more information, we can read our guide on Parental Controls and Parental Controls on PC and the Internet: 5 Ways to Keep Kids Safe.

How to block access to adult sites from smartphones and tablets

Do we wish to block access to sites from a smartphone or tablet with an Android operating system? In this case, we can use one of the many parental control apps, such as Norton Family parental control.

Thanks to this app we can set up an effective filtering system for each app inside the device: the minor will not be able to download apps that are not suitable for him and he will not be able to browse the categories of sites that we will block from our parent account. The app cannot be uninstalled without permission, thus making it an effective control system for minors.

If we are looking for something integrated with the Android system, we can also try Google Family Link, available as a parent app, and an app for children and teenagers.
Google Family

With these apps, we will be able to set app blocks, time limits for the use of the device, and also block sites not recommended for minors, all manageable through Google Family accounts (we can also receive notifications and permissions from our phone if we are in another room).

If we want to block access to sites from an iPhone or iPad we will not have to install any third-party app, being able to use the same menu seen on the Mac. To configure it, open the app Settings, we press on the menu Usage time, we press on the menu Content and privacy restrictions, we activate the voice present at the top, we press on Content restrictions and finally, we press on Web content.
IPhone time

In the window that appears we press on the item Limit adult websites, so as to immediately activate the filters for minors, if we want to add sites to the block, just press at the bottom on Add website at Never allow.
To prevent the child from removing the block by himself, let’s go back to the path Settings -> Usage Time and we press on the voice Redeem “Screen Time” code┬áso that you can protect the settings from accidental or intentional modification.

To learn more about the use of these parental control apps, we can also read our guide How to limit the use of smartphones and tablets to minors.

How to block access to adult sites via secure DNS

In addition to the programs, extensions, and apps seen so far, we can block access to adult sites by relying on protective DNS filters, designed specifically to protect minors from sites that are not suitable for their age (including gambling and cartomancy sites).
To apply a DNS filter on a PC we will not have to do is open the IPv4 settings of the Wi-Fi connection or Ethernet connection is set up DNS servers of companies offering protective filters.

If we have never changed the DNS servers on the computer, we can do this by reading our guide How to change DNS.
After gaining access to the screen seen in the image above, let’s add the protective DNS servers by choosing from those available below:

  • OpenDNS FamilyShield: 208.67.222.123 is 208.67.220.123
  • CleanBrowsing: 185.228.168.10 is 185.228.169.11
  • Norton ConnectSafe: 199.85.126.30 is 199.85.127.30

If we want to apply these filters also from an Android smartphone or tablet, just use the app dnspipe, available for free from the Google Play Store.

The protective DNS filters are among those present in the basic list included in the app: all we have to do is select them, authorize the VPN connection (actually it’s a trick to filter Internet requests, it’s all local) and enjoy the new DNS protective.

If we use an iPhone or an iPad we can quickly change the DNS using the app DNS Changer, available for free from the App Store.

The app allows you to apply protective DNS on all types of connections (network and Wi-Fi), so you can protect devices at any time of the day.

To learn more, we recommend that you read our guide How to change DNS on Android and iPhone.

Conclusions

Blocking access to adult sites or sites that we do not want to be seen by minors is relatively simple, just use one of the methods provided in the guide and adapt it to our needs as parents. At the time of writing, the simplest methods involve using the parental controls included in Microsoft Edge or using one of the extensions seen for Chrome and Firefox.
From mobile, on the other hand, it is always advisable to rely on the methods integrated into the device (on iPhone and iPad) or, alternatively, use the apps developed by Google to keep minors in-band (on Android).

As a form of control for PC, we can also use the tools seen in our guides block sites on your PC or limit time on Facebook, Youtube or others is how to block websites on smartphones.
