According to SPARC (the Scholarly Publishing and Academic Resources Coalition), "Open Access is the free, immediate, online availability of research articles coupled with the rights to use these articles fully in the digital environment. Open Access ensures that anyone can access and use these results—to turn ideas into industries and breakthroughs into better lives."
Here is a great article that goes into more detail: "What Is "Open Access"?"
Unpaywall is a Google Chrome web browser extension available for free at http://unpaywall.org/products/extension.
How it works
When a user lands on a paywall-blocked scholarly resource's webpage, if there's an open access version available somewhere else on the web for free that Unpaywall has previously located, a neon green icon will light up on the right side of the user's screen. Click on it, and you will be redirected to the freely available version of it! This is a legal and legitimate way to find scholarly content if you are performing open web searching (e.g. Google Scholar).
Open Access Button allows users to avoid paywalls and request research to get free, legal research articles delivered instantly. If the article isn't located for you in an OA repository, it will give you a hyperlink to request the article for free from the author(s). (You can see which aggregated repositories they pull their resources from at: https://openaccessbutton.org/about.)
How can I use it?

"There is an imminent danger of all new knowledge getting locked up and released into the public domain only when the middlemen publishers get rich enough. Released only when the knowledge itself is reasonably old and loose [sic] their cutting edge, especially for the economically tender third world." (Narasimhan, 2012).
There is a broad argument to be made, and that is already being made by many respected librarians, scientists, scholars, and researchers, that opening access to research is a moral imperative for humankind, and that urgency is compounded for those without the advantages of information privilege, which is "the idea that the information that one has access to is largely dependent on one’s status, affiliation, or power. " (Harmon, 2018)
