What Is password synchronization?
Password synchronization is defined as any process or technology that helps users to maintain a single password on a given set of systems in one single security policy, this rotates on singular basis and is one of the most effective mechanisms for addressing password management problems. However, in recent articles we spoke a lot about how ease of use or exceptional functionality usually comes at a price. I feel that password synchronization could be very dangerous to a large proportion of people.
Advantages of Pass Sync:
- Simpler way to manage passwords so..
- less calls to the help desk.
- money saved.
- Users with fewer passwords are less likely to write them down (thank god).
- Ease of use.
Disadvantages:
- If one system is compromised all systems are potentially compromised also.
- (Can turn out to be very expensive and damaging if executed badly).
- High Risk
Password synchronization is much easier to implement and is more effective against password management problems than enterprise single sign-on (or SSO), as there is no client software deployment, and user enrollment can be automated. There is also no single, critical point of failure in a password synchronization system, as the system is not involved in user sign-on processes
Sync Types
- Transparent password synchronization, which is triggered by a change of password on existing systems. The password will be automatically sent to the other user objects in parallel systems, which allows for significant modularity, yet integration (without user knowledge in some cases). Certainly an effective way to manage your passwords.
- Web Based Password Synchronization is triggered by the user with a commercial web browser, instead of the native process being used, a new one is put in its place which allows the user to set multiple passwords at once.
Obviously a system such as this is a dream for a hacker. None the less, at least there are less hashes to be found 
, but whether that is a good thing, I really could not say
