Hello,

Your OpenAI account is currently secured with SMS-based Two-Factor Authentication (2FA). Beginning January 1, 2026, SMS 2FA will no longer be supported.

To maintain uninterrupted access to ChatGPT and other OpenAI services, you must update your account to use an authenticator app or hardware token. Please update your 2FA settings at: https://auth.openai.com/settings/security

Thank you for taking action to keep your account secure.

Best,
The ChatGPT team
