The password you decide to use should be chosen in such a way that nobody else can guess it. A secure password is ideally a minimum of 8 characters (preferably longer) in length and a mixture of letters, numbers and characters. You should never use a dictionary word or anything which might be associated with you (eg. birthdays, pet names etc.). You should select a password that only you can memorise – do not write it down anywhere. Do not select a password that is the same as your irishrail.ie account.
