Side remark: All the methods exposed here requires you to have a good password. In my case, I am using a Yubikey set with a single long fixed password on it + the normal password I can remember. So, to login/unlock, I type in my password, plug the Yubikey and press the button. This ensures I have a really strong password. Because if your password is "1234password", all the provided solutions are of no real use.
