Custom domains
Serve your xyst.wtf page from a domain you own, with the DNS records it needs.
How it is sold
Your page can answer on a domain you own, with your name in the address bar instead of ours.
Buying again adds another year to whatever you have left rather than starting over, and Premium includes the first one. The domain itself you buy from a registrar; this is what points it here.
The records to add
Two records at your DNS provider, both shown with their values in your dashboard once you add the domain.
The CNAME is what sends visitors here. The TXT is the proof the domain is yours, and it carries a token belonging to your claim alone, while the third record is what lets us keep your certificate renewed without asking you again.
Verifying and going live
Once the records are live, your dashboard checks them and issues a certificate. DNS changes take as long as your provider takes, so a domain that is not verified yet is usually waiting on that rather than on us.
An apex domain (yourdomain.com with nothing in front) works, but many providers cannot put a CNAME there. If yours cannot, use a subdomain such as links.yourdomain.com.
Living on your own domain
Your page answers on both addresses. The xyst.wtf one keeps working, and it stays the canonical address a search engine is told about, so the two are never indexed as competing copies.
Signing in and your dashboard always happen on xyst.wtf. A visitor who follows one of those links from your domain is sent here for it.
