Change Your Password When You Change Your Clocks on March 14

Change Your Password

To protect your privacy and security, ITS recommends that you change your UMICH password for security about once every six months. A good way to remember to do this is to do it when you change your clocks for Daylight Saving Time. This year, Daylight Saving Time begins Sunday, March 14.

Check Your Computer Clock

It is essential that your clock have the current time if you use programs and services that require Kerberos authentication. If your clock is off by more than five minutes, you won't be able to log in to many U-M services.

Kerberos authentication allows you to authenticate—or prove your identity—when using computing programs and services. For authentication to work properly, your computer's clock must be synchronized to within five minutes of the clock on the server to which you connect.

If your computer is set to automatically download patches and software updates, and it is set to automatically adjust for Daylight Saving Time, your computer clock should make the change by itself. If, however, you need to reset your computer's clock, follow the appropriate steps below.
