Symptom

An administrator account may have been created without legitimate approval.

For: Site owners and agencies who found an administrator account they do not recognize.

Diagnosis

What to check before changing the site

Quick Diagnosis

First determine whether the account is undocumented-but-legitimate or truly unauthorized.

Incident Handling

Do not stop at deleting the user. Investigate how it was created and whether other persistence remains.

Evidence Before Removal

Record the user ID, email, role, creation date, last login if available, and related access logs before deleting anything. That evidence helps distinguish a forgotten agency account from active compromise.

Recovery Boundary

After removing unauthorized access, rotate administrator passwords, invalidate sessions, review plugin/theme changes, and check file integrity. A suspicious admin is often a symptom, not the whole incident.
