Passwords expire once a year! If you have not changed your password in the last 365 days, it will expire.
Gannon University email, public and assigned PCs, and websites -- are all shared resources. To ensure that they are only used by Gannon faculty, staff, and students, we require you to login before you can use them. Your Gannon email or Network ID (depending on where you're signing into) and password are your tickets to using any of these resources.
When you login, you provide two pieces of information: first, your Gannon email to identify your account, and second, your password, to confirm that you are the account’s owner. Your Network ID/email is public knowledge and is published in the Gannon online global address book -- so you must make sure that you keep your password private.
