At school the children are constantly reminded to keep their passwords private and to not let anyone else know them. This is very important advice for children and adults – a known password can allow someone to access your private information, assume your identity and even steal your money by accessing bank cards and online payment systems.
There is lots of advice out there on what makes a good password and often it is conflicting, but most experts agree that passwords should be complex enough to make them difficult to guess (no names, number strings etc.) but simple enough that you can remember them without writing them down. They should also, wherever possible, contain capital and lowercase letters, number and other characters.
Some examples of good passwords (although not anymore as they’re here!) might be a phrase (!10veMum), an acronym (T0andtPC – the owl and the pussycat) or two random words together (sh33Ptabl3). It would be almost impossible to have a unique password for every site you use even though it’s best practice, but the same core phrase with different letters or numbers depending on the site is a good compromise.
It goes without saying that if you suspect anyone knows your password/s you should should change them immediately.
