Password security: past, present, future

In this presentation, I start by providing some historical background on password hashing (since 1970s), show how today's password hashing methods are different yet similar, and finally propose how future password hashing methods may be designed (last 9 slides). I also briefly touch related topics such as password policy, rainbow tables, GPUs, multi-factor authentication, and I show how passwords (or rather passphrases) will remain relevant for many years to come. - Solar Designer
