Storing passwords securely is an ever-changing game. For the past few years (2013 –> 2015), Jean-Philippe Aumasson has been running a world-renowned Password Hashing Competition in which security researchers submit, validate, and vet the best password hashing algorithms.
Just recently, the competition wrapped up, naming Argon2 king of the hashing algorithms.
