The following sections describe whether each of the authentication methods is supported by cybozu.cn.

SAML authentication is supported by cybozu.cn.
Thus, users can single sign-on into kintone with user accounts registered with your organization's IdP.
SAML Authentication is available regardless of your kintone license plan.

In cybozu.cn, APIs to import user and department information are provided.
