Passwords are a nuisance: they are easily forgotten because firstly, we seem to need so many of them, secondly, we are forced to change them periodically and thirdly, it can be difficult to think of a decent one that you can remember easily.

Unfortunately though, they are most companies' main protection against hackers or other unauthorised access to their data, so we have to use them effectively.

The worst thing about passwords is that in practice, and probably because of the fact that they are a nuisance, they are relatively easy to crack.

All passwords should be easy to remember but difficult to guess. Some firms force their users to have passwords like Jk8Y77$%Ws which would be impossible to remember without writing down so it is useless in real life.

Our top tips to for creating secure passwords

1. Don't use a word you can find in the dictionary or the name of any person or place in any language.

2. Use at least mixed numbers and letters, or better still, use numbers, letters, punctuation and mixed cases.

3. Use a scheme like one of the following to make your passwords secure yet easy to remember:

  • Use the initials of a book you read or film you saw recently:

  • Ofotcn (One Flew Over the Cuckoo's Nest)

  • LotRT2T (Lord of the Rings: The Two Towers)

  • Use numbers 0,1,2,3,4,5 to replace letters O, L, Z, E, A, S to make normal words more complicated:

  • Ban4n4, sk1pas5. f00tba11, 2eta-J0nes

4. Or join two unrelated dictionary words together to make a new word and add a number to make it even harder to crack. (This is probably the easiest method of creating a hard password). Examples are:

  • Screen9sail, gameDog123, fish2fire

5. Keep a "public" hard password to use on non-critical things like websites where you have to register but which contain nothing really important. You will probably never be asked to change it so using the same password for ever for this kind of thing will reduce the number you have to remember.
