0. [Resolved] Outcome and Final Conclusion (Updated December 2025)

Regarding this issue, I have finally successfully logged in and resolved the problem. I would like to share the conclusion with those who visited this article facing similar circumstances.

Results of Support Consultation and Investigation

Initially, I requested an investigation through Billing Support to a specialized team. However, it took considerable time to coordinate the scope of responsibility between departments (Billing Team ⇄ Technical Team). Ultimately, I was informed that the "Technical Team could not investigate as it was outside their scope," and the case was closed with a suggestion to use the official community forums.

The 7-Day Waiting Period

However, immediately after the support interaction ended—approximately 7 days after the error first occurred—the situation improved after I refrained from any operations. The 2-Step Verification (2SV) process, which had previously blocked me with the "We couldn't verify it's you" error, successfully went through. I was then able to configure my security settings and log in to Google Cloud.

Based on the login history, the presumed factor for resolution is: "By refraining from login attempts for a certain period, the system's security lock was automatically lifted."

Tackling Rising Storage Costs in Artifact Registry

When using a CI/CD pipeline with tools like GitHub Actions to deploy to Google Cloud Run, a new Docker image is pushed to Artifact Registry with every run. While this is a very convenient system, old images will pile up if left unchecked. Have you ever been surprised by a higher-than-expected storage bill?

This article introduces how to solve this problem using Artifact Registry's "Cleanup Policies" feature. I'll provide a step-by-step guide on how to automatically delete unnecessary old Docker images to continuously optimize your storage costs.

This guide is based on the Google Cloud Console UI as of July 2025.
