Old user accounts are easy to ignore.
They do not make noise. They do not trip breakers. They do not look messy in a rack. They simply remain in the system.
That is exactly why they should be reviewed.
Access often outlives the reason it was created
A guest needed access for a holiday. A contractor needed temporary Wi-Fi. A staff member needed CCTV viewing. A previous manager needed app control. A service provider needed remote access.
At the time, each account had a reason.
Months later, that reason may no longer exist.
Old access is a privacy issue
In private homes, technology access can be sensitive.
CCTV may show family movement, staff routines, driveway activity or private spaces. Smart-home apps may control lighting, music, gates or scenes. Wi-Fi access may provide a path into networks that should not be shared casually.
Even if nobody abuses old access, the risk is still unnecessary.
Reviews should be scheduled
Access cleanup should not depend on someone remembering at the perfect time.
It should be part of a periodic support review, staff-change process or annual technology check.
The owner or authorised contact should confirm which users still need access and which should be removed.
Removal should be documented
When accounts are removed, the support note should record what was removed and why.
This protects the client and creates clarity if someone later asks why their access no longer works.
The process should be calm, professional and traceable.
DG Technologies treats old access as part of maintenance
Maintenance is not only cleaning cameras and checking racks.
It is also checking whether the system still reflects the people who should be using it.
Old accounts are not automatically a sign of convenience.
They may simply show that nobody has reviewed the system for too long.
