i think one way could be if you have a coworker or someone who is able to get root on the machine you are trying to log into. if you have the same password on your own machines sshd he might even easily get back to it and read credentials stored in your browser or use your credentials to damage some part of the comapny in your name etc... Might be somewhat far stretched but it is definitely something one should be aware of.
