Hey @doublesharp,
I could do. However this leads to the question of how much of the plugins functionality are we bypassing. Likely answer is most of it.
The idea would be that I’d write you a filter that would give you the username and password from the form and you would return user data in a valid format if they were authenticated and maybe false if not.
This begs the question, what is the plugin actually doing for you?
The rest of the logic is really simple so you may prefer to just include the custom code yourself.
The plugins core logic of that part of it was all based on this blog post by Ben Lobaugh:

I’m certainly not saying I can’t do that for you – and I’m happy to look into it if you’re keen. But it won’t be saving you much.
Any thoughts?
