There is always NJ Transit Bus. I dont live in Passaic and have no idea where the Passaic Bus Terminal is, but a quick search on the NJ Transit site shows you can catch a bus at 10:10 and be at Passaic Bus Terminal in less than 50 minutes. There are also options to catch bus back to Port Authority and get bus back out towards Passaic. They run a lot more often than the Suffern Line that late at night.
