In order to log into your HOL account, you must have your password and your HOL ID. When you first signed up, you created a password for your account.
If for any reason you ever need to change your password, go to My Profile, My Settings, Change HOL Password. You will need to enter your old password along with the new one. It is recommended that you change your password every 3 months for security reasons.
If you cannot remember your password, you may post in Prof. Kimil's Office in Forgotten Hol Office Passwords, Post here ONLY.
