Your password should be easy for you to remember, and difficult for someone else to guess.
This system can automatically choose a random password for you if you leave the field blank when you sign up.
It is generally a bad idea to use any english words (or combinations) as your password as these cah been easily found by a brute force search through a dictionary.
The best passwords, like the one the system will automatically generate, consist of a mix of upper and lower case letters and numbers - these are virtually impossible to guess. However, they may be difficult to remember.
