How do I change the password of my main Google account on a Droid X?

I changed my Google Account password (on my computer). I now need to change it on my Droid X. I cannot figure out how to do this. I Googled, and everyone says go to Settings > Accounts. I did this, but there is nowhere to change the password there. It only specifies four services that are syncing. "Contacts" is throwing an error now, but, still, there is nowhere to change the password.
