Nikon has updated two aging DSLRs with firmware updates to fix potential password vulnerabilities, so if you have either a Nikon D500 or Nikon D5600 then you should update their firmware at the earliest opportunity.
The midrange APS-C sensor Nikon D5600 gets firmware version 1.20. This update from the previous firmware version 1.10 changes the default password that is displayed in the network connection function. Once the new firmware has been applied, selecting Setup Menu > Wi-Fi > Reset Connection Settings will change the default password.
