The 'Challenge Passage' is another site owner configurable setting and it ranges from 5 minutes to a year (I believe the default is 30 minutes).
Basically Cloudflare has heaps of settings for everything they do, most of the things people complain about are on the site owner, usually not Cloudflare.
There's also Privacy Pass, which stores the result of your CAPTCHA for the next 30 CAPTCHAs IIRC, but as you might guess, the site owner can disable it.
