I've done so within the last year, successfully. Cost $7 for a single password in just compute and took about 17 hours (lowest, cheapest priority).

So please explain your reply further. Also recall their claim for context of what I was replying to, and what you're here defending now.

If their claim is credible what I did and what you're reiterating wasn't possible.

No you haven't, not for a reasonably strong password.

You brute forced a random argon2 hashed password using cheap compute in 17 hours?

Granted the suggested defaults for argon2 is like ~0.1 second per verification on a rather beefy CPU, in 17h that's about 620 000 guesses.

Your cheap compute would likely perform worse.

That is beyond improbable. You are making it up.

Your story lacks important context. Was the password "password"? "123456"? Or a 12-character mix of cases, numbers, and special characters?
