Zittme has built-in social login for Google, Kakao, and Naver. You just turn it on in the admin, without installing a separate module. It is off by default.

What you need

You need to create an app in each service's developer console and get keys.

Register the following address as the redirect (callback) URL in each console.

https://내도메인/index.php?act=procMemberSnsCallback

How to turn it on

1. Go to Admin > Members > Social login settings.
2. Turn on the services you want to use and enter the keys you received.
3. After you save, login buttons for those services appear on the login screen.

How it works

• When someone logs in with a social account for the first time, they are signed up at the same time. If the email matches an existing member, it is linked to that account.
• Members can link additional social accounts or unlink them on the Connected services screen in My page.
• For members who signed up only through social login and have no password, social re-authentication replaces the password confirmation step when editing their info or withdrawing.

Common problems

• The callback returns an error: Check that the redirect URL registered in the developer console exactly matches the address above (including https, domain, and parameters).
• The button does not appear: Check that the service is turned on in the social login settings and that its keys are saved.
• Test in a private window. If you already have a logged-in session, the flow may look different.
