Custom Admin Panel Access Recovery

I’m locked out of a completely custom-built admin panel and need to regain control as quickly and safely as possible. The usual password-reset flow no longer works, and I do not have direct database access to reset credentials from the backend.

You’ll be given whatever server-level access is required (SSH, FTP, or similar) once we start, along with a full copy of the codebase. The job is finished when I can log in as an administrator again and the live site is operating exactly as before. A brief, step-by-step note of the actions you took is also expected so I can prevent the same issue in the future.

If you’ve rescued locked-out systems before—especially custom frameworks—let me know how you approached them and how quickly you can begin.
