When you setup your router or any Internet Connected Device – what is the 1st thing you should do ?
Change the default login and password.
Many internet connected devices will have a default user name and password such as:
user name:admin
password:admin
or
user name:admin
password:password
This will mean that in many cases it will be very easy for someone to take over the device so when you are setting it up , change the user name and or the password to something unique.
