Students have an email address with the domain of ''"learn.senecac.on.ca"'' and professors have an email address with the domain of ''"senecac.on.ca"''. User ID for both login types are is their respective email prefix. For example a user with the email address of ''johndoe@learn.senecac.on.ca'', will have a user id of ''johndoe''. Each user's initial password will be e-mailed to them upon creation of their account by the system, the default password may be changed at any time by using the "Change Password" function (see [[#Change_Password_Function|''Section 3.1.2 Change Password Function'']] for details).
