Like JSON? I think for some acronyms, JSON and JWT included, those are their "proper" names, with the expanded name being just a curious historical note.
Then at least link the first instance to the Wikipedia page or something. After reading the first couple of paragraphs I had no idea what this article was about.
I'd say it's good writing to link to the wiki entry for a less common concept like JWT in the first paragraph, right next to where they first mention it. It's definitely not ubiquitous like JSON, SQL, or FBI.
