Square Enix warns of unauthorized logins to Square Enix Accounts
Square Enix says leaked credentials from other services were used, and that some accounts have already had login restrictions applied.
Square Enix posted a notice titled "Caution Regarding Unauthorized Access and Account Management" on The Lodestone, the official Final Fantasy XIV information site, warning that unauthorized logins to Square Enix Accounts are taking place. The notice was also shared through the official Final Fantasy XIV X account FFXIV_NEWS_JP (@FFXIV_NEWS_JP) on October 19, 2026, according to gamespark.jp.
The company said it has confirmed cases of unauthorized logins using email addresses or account IDs and passwords believed to have leaked from other companies' online services. Accounts suspected of unauthorized access have already had login restrictions applied to prevent further damage.
