Using your own domain

Serve your site from yourdomain.com (paid plans).

Open your site settings and enter your domain, for example photos.yourname.com.
At your domain provider (where you bought the domain), add the DNS records ShotLocker shows. Each record has a copy button for its name and value.
Come back and verify. Once it passes, your site is served from your domain, with HTTPS.

Your yourname.shotlocker.app address keeps working. Custom domains are on paid plans.
