By default a verification link opens on idv.proofage.net. With a custom domain it opens on a subdomain of yours, for example https://verify.example.com/q/AB12cd34Ef, so the person sees your name in the address bar. You add one DNS record; ProofAge issues and renews the certificate.

​
Add a domain

  1. In Settings, open Custom domains.
  2. Type the subdomain, such as verify.example.com, and choose Add domain.
  3. At your DNS provider, add the record the console shows:
  4. Wait. The status changes to Active once DNS has propagated and the certificate is issued, usually within minutes. Check now looks again at once; the console also checks on its own every few minutes.
If the certificate is still pending after about half an hour, the console shows a second record. Add it too, and keep it: the certificate renews through it.
Only an administrator can add or remove domains.

​
Which names work

  • A subdomain only: verify.example.com works, example.com does not. A domain’s own apex cannot hold a CNAME.
  • No wildcards (*.example.com) and no IP addresses.
  • Up to 5 domains per company. A hostname can belong to one company only.
  • If your domain has CAA records, they must allow the certificate authorities Cloudflare issues from, or the certificate is never issued and the domain stays pending. The errors shown under the domain name the CAA problem.

​
Statuses

A domain that stays Waiting for DNS for 72 hours is removed and shows Failed. Fix the record and choose Retry to start again; the same applies to a hostname that was dropped. A domain that failed this way does not hold the name: another company can add it. If the status says Cloudflare blocked the hostname, contact support. Your fallback is idv.proofage.net.
  • Your first domain becomes the company default. Make default moves it to another domain, Unset default clears it. Every workspace follows the default unless you choose otherwise.
  • On a workspace, Link domain offers the company default, the ProofAge domain, or one specific custom domain. Administrators and developers can change it.
Only an active domain goes into a new link. While a chosen domain is not active, new links use idv.proofage.net, and the console says so. Switching the domain never breaks a link you already sent: any active domain of your company opens any of your workspaces’ links.

​
Remove a domain

Removal stops new links from using the domain at once, and a removed company default is no longer the default. An active domain keeps answering for 7 days, so links already sent keep working; the console shows the date it stops. A domain that is waiting or failed is deleted immediately.

​
Embedded mode

If you open the verification in a frame on your site, add the custom domain to frame-src in your Content Security Policy, next to idv.proofage.net.
