The best protection is a strong passphrase. This is a password made up of three or four random words – for example, ‘purplecakedinosaurmoon’ is a very tricky password for others to guess but easy for you to remember if you make a picture in your mind – a dinosaur on the moon eating a purple cake!
You should try to use a different password for every account and device – so even if someone guesses your password for one account, they can’t use it to get into your other accounts.
Your passwords belong to you – you shouldn’t share them with anyone else, even your best friends. The only people who may need to also know your passwords are a parent or carer.
