- You cannot log in to the web interface (password unknown).
- The device rejects the password you believe is correct.
- You inherited a unit and were not provided the password.
- Incorrect settings selected in WinDiscovery for the intended behavior
- Signal integrity issue (cable type and length, connector seating, grounding/shielding, or signal level)
- Physical installation factor (cabling, connectors, or power), temperature and humidity are rarely the cause
- Perform a factory reset on the device.
- After reset, log in using the default credentials (if applicable) and set a new password.
- If you manage many units with the same password, use Global Password in WinDiscovery as a convenience feature.
If you cannot perform a factory reset due to access or physical constraints, contact Masterclock Support.
Masterclock devices that support passwords do not provide a password readout or recovery mechanism. If the password is lost, you must return the unit to a known state by performing a factory reset.
Global Password in WinDiscovery does not change the device password by itself. It simply helps you avoid repeatedly typing the same password when multiple devices share the same credentials.
This applies to Masterclock products that support password-protected access (for example GMR, NTDS, NTP100, and RC). It does not apply to products that do not support passwords (for example DA12 or PSU45).
