A sensible precaution when mucking around with things that could affect your account's login is to ensure there's a second account you can log into in case you break the first one. Also, ensure that the second account can run either "sudo" or "su" or some other privilege elevation command, so that you can fix the first account from the second. (Of course, if the second account is root, then no elevation is needed.)
