Password synchronization is an authentication process that coordinates user passwords across various computers and computing devices so a user only has to remember a single password instead of multiple passwords for different machines or devices. Some versions of password synchronization, such as single sign-on, also enable password coordination across applications.
Password synchronization typically increases security by insisting on the use of strong passwords that cannot be easily guessed.
