Locked out of ZyWALL USG 100
Options
Lost power in office and when my ZyWALL USG 100 powered back on it will no longer accept my login password. I have also tried the default password. The Unit is working just fine and the VPN is working without issue. Is there a way I can access this unit from the rear AUX or Console port to reset the password? If so, what would the procedure be?

Do you have a config backup?
If you do, I suppose you can reset if, and then upload the backup config (after removing admin password).

Hi @Ricky,
If you don't have backup configuration, you can follow the instructions in the FAQ to recover the configuration file and reset the password.
