As of now, you can choose whether your registry is searchable through search engines and on Zola. Unfortunately, we do not yet have an option to create a password for your registry.
To update your registry preferences, click into your Registry Settings page when editing your registry–you'll find the option to exclude your registry from search at the bottom.
Please note that if you choose to not show up in search engines, you'll need to provide your guests with a direct link to your registry in order for them to find the registry itself!
Pro-tip: If you make a wedding website with us (which you should!), you have the ability to password-protect that website.
