OpenAI alerts ChatGPT API users about possible data breach

Technology Nov 28, 2025

OpenAI has informed some ChatGPT API users about a potential data breach linked to Mixpanel, the analytics tool used for its API dashboard.
The good news: this doesn't affect the main ChatGPT app or your chat histories and passwords—they're safe.
Only certain API account details might be involved.

What's at risk and what's next

Some profile info like names, emails, and browser details could have been exposed—potentially even for Apple employees using the API.
OpenAI quickly dropped Mixpanel and started a full investigation. They're reaching out to organizations just in case, promising transparency as they keep looking into what happened.
If you use the API, it's a good idea to stay tuned for updates from OpenAI.
