2.1.2 The ‘WEB Authentication’ submenu 
Use the submenu to assign passwords for administrator and unprivileged user.  
TAU-8.IP  implies  two  types  of  the  users:  admin  and  user.  User  admin  (default  password: 
password) has full access to the device: read/write any settings, full device status monitoring. User 
user  (default  password:  user)  may  access  device  status  monitoring  without  reading  and  recording 
configuration  data.  Viewer  (spectator,  default  password:  viewer)  may  only  view  full  device 
configuration without editing privileges and access full device status monitoring. 
Administrator  password  is  used  for  administrator  access  via  Web-interface,  Telnet  and  SSH 
protocols. User password is used for unprivileged user access via Web, Telnet, SSH and FTP. Viewer 
password is used to view the device settings via Web, Telnet, SSH and FTP.
