Locked out of my own Google Cloud project — no access and no support options

Hi Andrey,

It sounds like you’re encountering a common issue related to ownership and IAM permission loss within Google Cloud. When a project is created under a personal Google account, access can sometimes be lost if ownership tokens expire, permissions are reassigned, or the associated billing profile is flagged or deactivated.

Here’s a structured approach you can take to recover your access:

1. Verify Project Ownership via the Cloud Resource Manager API

   • Use the command:

     gcloud projects describe PROJECT_ID

     This helps determine whether the project still exists under your account hierarchy.

2. Check Billing Association

   • Visit Google Cloud Billing Console → Manage Billing Accounts → select the account → “View Linked Projects.”

   • If your project is linked, you can raise a billing support ticket, which often helps in re-establishing ownership verification.

3. Attempt OAuth Re-linking

   • Since your use case involves Gmail API authorization, ensure that your OAuth Client ID and consent screen settings remain valid in the API Credentials section:
     https://console.cloud.google.com/apis/credentials.

4. Manual Project Recovery

   • If none of the above resolves the issue, submit a Project Recovery Request through Google Cloud Support. They will request verification details like Project ID, Billing ID, and original creation metadata.

At Cyberphore, we’ve assisted multiple clients with similar Google Cloud IAM and access restoration challenges, particularly around OAuth configurations and API authorization issues. A structured permissions audit and domain-based verification typically resolves such cases.
