1.6.4 Combined Verification
To increase security, this device offers the option of using multiple forms of verification methods. A total of 11
different verification combinations can be used, as shown below:
Notes:
1 "/" means or, and "+" means “and”.
2 You must register the required verification information before using the combination verification mode,
otherwise the verification may fail. For example, if a user uses Face Registration but the verification mode is
Face + Password, this user will never pass verification.
