May i suggest my own secure system: It is well known that the weakest part in any security system is the password, not many remember them and most of the people (especially the average ones) just hand write them and stick on the monitor. Solution- create a system of your own inside your brain to remember a password, do not use a software, application, stick note or else. use your own brain.
