The password is NOT blank for Telnet and SSH through port ge-0/0/0.
However, password is blank for web site and console.
This persists even after reset.
Not sure what Juniper is doing. Perhaps they fear SSH or Telnet (can't say I blame them for fearing Telnet)? Maybe that is turned off intentionally?
Our procedure is to now use the console for configuration.
