Setting your login password

IMPORTANT: Your Mac must have a login password that is compliant with Cornell Policy 5.10. To ensure that your login password meets Cornell’s security standards, you may test it here:

When you have created a password that meets all of the requirements, you may then set it as your computer's login password. To do this, follow these steps.

Make sure that the password you choose is not the same as the password for your personal account and is compliant with Cornell’s passwords strength guidelines. (You can check your password’s strength here:  Since you will log into the Administrator account, be sure to write down the password for it in a safe, secure location.
