That's not what was paraphrased.

I believe that a related idea, "Don't roll your own crypto[graphy]", is widely accepted good advice.
Authentication in Web systems overlaps with that, and has a bit of the same nature.
Though the nuances in Web systems aren't as hard as the nuances can get in cryptography math and protocols, and in computer implementation of same. Still, it's much harder than it looks, to get sufficiently right. Most people don't have time for that.
Personally, I take both seriously. I don't touch cryptography implementation myself directly. And lately (as I said in the original comment), I'm trying to use off-the-shelf Web authentication. Because, as I implied, it's hard get all the nuances right.
Aside: "Dunk on" of other commenters sounds to me like contemporary social media personal attack sport, which I'm trying to avoid on HN. When I stopped by HN on Saturday morning, to get a little startup business mindset/enthusiasm, before spending the day working on an indie Web project, I wasn't looking to have a reasonable assessment called "insufferable", by some random new account. (A new account of someone who seems to be having a bad day, and getting off on the wrong foot with HN, with every single of their 6 comments attacking other commenters.) And then, after I tried to respond reasonably constructively to them, some other person, who might've misread the situation, jumps in, to double-down for the new account. Maybe all 3 of us would like to start the day over, and not spread bad day contagion further?
