Daybreak Blue. Does OpenAI require one or two physical security keys after September 1?

I was approved for Daybreak Blue today and I’ve already enabled Advanced Account Security. My current setup is: iCloud/iPhone passkey Windows Hello passkey Advanced Account Security enabled What I’m not completely sure about is the new requirement for individual Daybreak users starting September 1, 2026. OpenAI’s Daybreak announcement says: “We are requiring all individual accounts in Daybreak to adopt hardware security keys, beginning September 1, 2026.” But the Daybreak troubleshooting documentation is more specific and says individual users must: “configure a FIDO-compliant physical security key by September 1, 2026.” The second wording seems to indicate that one physical FIDO key is sufficient, provided the account already satisfies the separate Advanced Account Security requirement for multiple authentication methods. But I am not sure. Has anyone received more specific information from OpenAI about this?
