Secure Passwords – An Idea

How can we have a secure passwords which are not easy to hack but also easy to remember? I was thinking about it and thought I would share a idea which I got recently. How about making the password a square root of some number? For example – I can  say my password would be square root of number 786 which is – 28.035691537752372695618339855308. This way, I don’t have to remember my password and it’s not hackable and a calculator is easily available on all the computers I access.

I know that different computers might give out different number in the fractions, so I can agree that I would just take first 10 characters as my password. That way I avoid all the problems with fractions. I can’t think of anything else that might be very wrong with this idea. I mean, yeah if people were looking over your shoulder they would know your password but this trick could be used for some extremely annoying accounts like online registrations for NYT or Fandango etc.

We can  expand it and make it Cosine of it or Tangent of the number. Or for an advanced user may be a MD5 sum of a number. We can build a Firefox extension which would computer a MD5 checksum of a number and give you the value and you can drag drop it in password field.
