You can disable 2FA by email authentication or UPR(User Password Reset) function.
– To use email authentication, the FEN setup must be configured.
– To use the UPR function, the UPR file must be saved in advance.
Please refer to the manual for more detailed information.

If the above two methods are not applicable, the factory reset of the NVR is required. Please contact techsupport@idisglobal.com for more information.
