Passwords
Someone must have got hold of Ellies password. What happened to her is just one example of the trouble it can cause.
You should treat your password like your toothbrush - don't share it, even with a best friend. You might fall out with them or they might secretly tell their best friend.
Keep your password safe.
The other thing you need to think about is whether your password could be guessed. If you use your pets name it's easy to guess and its called a weak password. A strong password includes upper and lowercase letters and also some numbers; perhaps even punctuation if it is permitted
The problem is that strong passwords are harder to remember so heres an idea; think of a senctence and then use the first letter of every word. The sentance will be easy for you to remember but no-one could ever guess the password it makes.
