Changing your password
One of the things you should do when you log in for the first time is to change your password.
The UNIX command to change your password is passwd:
$ passwd
The system will prompt you for your old password, then for your new password. To eliminate any possible typing errors you have made in your new password, it will ask you to reconfirm your new password.
Remember the following points when choosing your password:
Avoid characters which might not appear on all keyboards, e.g. '£'.
The weakest link in most computer security is user passwords so keep your password a secret, don't write it down and don't tell it to anyone else. Also avoid dictionary words or words related to your personal details (e.g. your boyfriend or girlfriend's name or your login).
Make it at least 7 or 8 characters long and try to use a mix of letters, numbers and punctuation.
