Step 1 of 3 · prove the domain

Claim encon.pl

Enter your work email at @encon.pl and we send you a single-use link. It works once and expires in 30 minutes.

A mailbox at @encon.pl exactly: no subdomains, no address at another domain.

No mailbox at @encon.pl? Prove it another way

Two more ways to show you control the domain, for whoever runs the website or its DNS. Each issues a token that stays valid for 7 days.

DNS TXT record

Publish one TXT record at _itha-challenge.encon.pl.

.well-known file

Put the token in the verification field of https://encon.pl/.well-known/itha.json. Fetched over HTTPS from that exact host; cross-origin redirects are refused.

If two people claim the same domain, the first token to pass wins and the other claims are superseded. Nothing is published until the facts are approved in step 2.
