Passport authentication/notarization

I work for a corporation in the U.S. that has an affiliate in China with a bank account at a local bank in Beijing to which I have online banking access. My online banking access will soon expire and needs to be renewed and the Beijing bank branch is mandating that I ship my original passport to them to complete the token renewal. I would prefer not to ship my passport overseas. Can the Chinese Consulate authenticate/notarize a copy of my U.S. passport so I can help the bank in Beijing get comfortable with me not sending my passport to them?
