OCI Free Tier sole administrator locked out after iPhone replacement – Live Chat MFA recovery loop
Summary:
I am the sole administrator of an OCI Free Tier tenancy.
I reinstalled my iPhone and lost my Oracle Mobile Authenticator registration. I have no bypass code and no other administrator.
I can successfully authenticate with my OCI username and password, but I am blocked at the MFA step because the approval request is still sent to my old device.
I still have SSH access to an existing OCI compute instance in the tenancy.
I have followed the documented Oracle procedure:
Get Support → Cloud Infrastructure (OCI) including Free Trial → Cloud Support Chat.
However, the chat does not transfer me to a Support Chat Engineer. It always returns the same automated "Lost Access to the Phone" instructions telling me to chat with a Live Agent, resulting in a loop.
