Part of it is that most of the libraries that came before we’re tightly coupled to a particular framework that itself went out of fashion, like Passport and Express, which is a problem because frameworks themselves have been moving in and out of fashion very rapidly; or are coupled with service offerings from vendors, like Auth0.

Auth.js is actually one of the first attempts that tries to be framework and vendor agnostic while still including a good deal of the batteries you need to make a full authentication system, which they only recently did, as they were originally tied to next JS like every other library in the graveyard of authentication libraries.

If you just want to specifically do an OAuth handshake or salt and hash a password or produce a JWT, those libraries are all rock solid. But a full batteries included framework and vendor agnostic solution hasn’t really existed until recently.
