Your computer must be configured so that when it starts up, you need to enter a password. This should be a strong password that is only used by you. It must not be the same password as your NetID password.
These requirements apply to all accounts on the computer. Any access to your system must be protected by a strong password.
The password complexity rules for NetIDs are a good guide to choosing a strong password. Your local department may enforce different (and more stringent) rules for setting your computer access password.
