If you want to operate safely online (of course you do) then you need to use good, secure passwords, but apart from the user names and passwords you may use to access websites it’s worth looking into some of the everyday devices we use to ensure they are also secure.
For example your home Internet router. It’s the device that lets the internet in and shares it will all your computers and other devices, but comes out of the box with a default user name such as “Admin” and a password like “Password”. Unprotected with a secure password someone could access your WiFi and even intercept anything you do online.
