Your login password is the password you use to log on to your computer (Windows OR Apple) AND your email account. You can help keep your email (and computer) more secure by changing your login password regularly and by using a strong password. For more information about strong passwords, see Tips for creating strong passwords and passphrases at Microsoft's website. Or the very informative info-graphic at the bottom of this page.
If you have forgotten your password you can contact anyone on the IT staff to have your login password reset.
