This looks promising, but I actually need a page with this on it to test. I think I can crack it, but only partially.

When verification is done, the website's back-end sends a webhook to an URL which is used for verification.

If a website checks for this then it can't be bypassed afaik, but if a website only listens to the events for completing the flow, then this can be bypassed.

Added in v1.1.1, although it's in early beta. Might not work at all on most sites
