# Custom domains

Open your Lair at a domain you own, with Pro.

Canonical: https://help.lair.so/guides/custom-domains

## Add your domain

Pro includes one custom domain. You need access to the domain’s DNS settings. A subdomain such as `home.yourdomain.com` is a good starting point.


1. Open **Settings → Domains**.
2. Enter only the hostname, with no `https://` or path.
3. Select **Add domain**. If connections are still being set up, check back when that message is gone.

## Add the exact DNS records shown

1. At your domain provider, add the CNAME and ownership TXT records shown in Lair. Copy the names and values exactly; they are specific to your connection.
2. Choose **DNS only** if the provider offers a proxy option. For a root domain, the provider must support CNAME flattening; otherwise use a subdomain.
3. Return to Lair and choose **Check connection**. Allow time for DNS and HTTPS to become ready.

The TXT record proves the domain is yours. Keep it while the domain is connected. If you see Waiting for DNS, check the record names, values and any conflicting records at that hostname.

## Choose your main domain

In **Settings → Domains → Main domain**, choose your original `*.lair.page` address or a connected custom domain, then choose **Save main domain**. Only verified, connected custom domains are available.

Your Lair, Google sign-in, Find your Lair and emailed address links open on this main domain. Sign in again when you switch addresses; sessions and passkeys belong to the address where they were created. Google Calendar authorization returns to the signed-in address that started it.

If a custom domain is removed, loses its connection or no longer has Pro access, your original address becomes the fallback. Resetting your Lair keeps your main-domain choice.

## Open and sign in

Choose Open main Lair to use your selected address. Sign in with an email code or Google, then add a passkey there if you want one. Passkeys belong to the address where they were created.

Your other Lair address sends visits to the main domain. Remove a domain in Settings → Domains before adding another. After removing it, clean up its DNS records at your provider. If Pro ends, the custom connection is released; use your original Lair address.
