OpenAI AI Updates: September 26, 2026

1. ChatGPT Adds a Security History Log for Account Activity

OpenAI added security history to ChatGPT on September 25, a log of recent sign-ins, sign-outs, and changes to multi-factor authentication, passkeys, and other security settings. Each event shows the time, location, and device, though some details may be approximate or missing. The view lives under Settings > Security and login > Security history on the web. Source

2. Business and Enterprise Admins Can Now Gate ChatGPT Sites and Ads Access

OpenAI gave global admins in ChatGPT Business, Enterprise, and EDU workspaces two new controls on September 24: whether ChatGPT Sites can use members’ connected apps, and whether applications can access ChatGPT Ads. Both permissions sit on a redesigned External access page in the OpenAI Admin Console and are off by default during the admin preview. Members still have to authorize access with their own permissions, and identity-only sign-in stays separate from data access. Source
