When you're at work and using work devices, you have no reasonable expectation of privacy. Just because you take the laptop home doesn't make it suddenly your personal device. It makes it a liability to you.
Never ever log in to a personal account for anything at work, because you shouldn't trust your work with your privacy. If you do, you should just know you need to immediately change your password because it's now on a cleartext log file somewhere where many humans can read it. Consider it compromised.
