Question
:
What can I do when forget password & User name? Or What is the password and user

Answer:
Normally When you see the user name "admin", and empty password, you can click "ok"
directly to enter the system , cause we didn't set any password for the system as default.
If you forgot the password you set by yourself, then you can try the follow solutions:
1. Please enter any numbers you like with user name and password, then you will get a error message said:
"User name/ password is incorrect" .

button of the mouse (about 8 times) till it appear which shows that you can restore default user, then you
can reset any user name and password you like.
