The Wi-Fi password lets a device join a protected wireless network. The administrator password controls settings on equipment managed through its local page. Some products instead or additionally use a manufacturer account and app.
Check the manual for the right access method. A sticker may show initial credentials, but they may have changed, and not every product prints both passwords. Keep administration credentials private.
Only change a network you are authorised to manage. Before adjusting security, note the existing setup privately, check device compatibility and plan how essential connections will be restored.
