Are you being serious here?

Let's do the math.

1200 lines in a hour would be one line every three seconds, with no breaks.

And your figure of 1200 lines is apparently omitting whitespace and comments. The actual code is 2626 lines. Let's say we ignore blank lines, then it's 2251 lines. So one line per ~1.6 seconds.

The best typists type like 2 words per second, so unless the average line of code has 3 words on it, a human literally couldn't type that fast -- even if they knew exactly what to type.

Of course, people writing code don't just type non-stop. We spend most of our time thinking. Also time testing and debugging. (The test is 2195 lines BTW, not included in above figures.) Literal typing of code is a tiny fraction of a developer's time.

I'd say your estimate is wrong by at least one, but realistically more likely two orders of magnitude.

An expert in oauth, perhaps. Not your typical expert dev who doesn't specialize in auth but rather in whatever he's using the auth for. Navigating those sorts of standards is extremely time consuming.
