An important part of the security of the SAL computer systems depends on your good work in choosing and guarding your password. When and Why , What , and How. When and Why to Change your Password Everyone should change their password periodically, usually every three to six months. Many systems enable the system administrator to forceusers to change their passwords after an expiration period. At SAL we do not insist on an expiration time, however this might be considered in the future.
Some systems provide software which forces users to change their passwords on a regular basis.
Many of these systems also include password generators which provide the user with a set of passwords to choose from. The user is not permitted to make up his or her own password. There are arguments both for and against systems such as these. On the one hand, by using generated passwords, users are prevented from selecting insecure passwords. On the other hand, unless the generator is good at making up easy to remember passwords, users will begin writing them down in order to remember them.
