Paywall articles are those items that require a subscription before you can access them or read more about them. To avoid these paywalls, you can use an incognito window to open the link. In Internet Explorer, you'll find it as a new InPrivate window. Paste the link to your article in the search bar of the Incognito window to read the article behind a paywall.
When you use a VPN service, your IP address will no longer be tracked and you'll be able to access an item for free. If you're looking for copied content, simply copy the news headline and paste it into your search engine along with (”). You can also try the Unpay Wall extension for Chrome, which searches the Internet for a free (legal) pdf version of the article you want to read. The VPN extension will help you get more than one IP by changing your location, this will allow you to read thousands of articles for free and will easily bypass the paywall. Some websites with paywalls allow readers arriving from Facebook to read articles for free, even if they don't have a Facebook account.
To take advantage of this loophole, open the article link in Facebook and then copy and paste it into your browser's address bar. An annotation service allows users to read articles without distractions. A free annotation service is Outline. This can work since most article paywalls are for users, not search engines; they usually want search engines to crawl all content. Finally, Reader Mode isn't technically a tool for bypassing paywalls (it formats articles differently to make the reading experience more comfortable and distraction-free, and includes dyslexia friendly reading tools), but it generally also succeeds in accessing content beyond the paywall.
